Sins of the Prophets Wiki

The space forces and support assets Covenant commanders have at their disposal.


As of SotP 0.90, it has been introduced a leader-based system which allow a distinguished style of play without necessarily changing faction. As such each leader can specialize in a certain type of play, but he's not constrained to it. Buffs received have no drawbacks, meaning there are no tradeoff traits for anyone involved. These buffs are received by a linear tech path split among multiple branches of research, spanning from early to late game. Three leaders are available for each faction.

Supreme Commander Thel 'Vadamee[]

Supreme Commander Thel 'Vadamee is the most offensive leader in the Covenant roster. Emphasizing traditional Covenant tactics, based on overwhelming firepower and swift strikes, he is best suited for significant attacks in both creative and direct ways. He is diametrically opposite to Imperial Admiral Xytan ‘Jar Wattinree.

  • +25% speed boost for 60 seconds - after exiting Slipspace

A particular justice
  • Turn rate: +20% - capital ships only
  • Fleet capacity: +100
  • Weapons range: +10% - plasma lance only
  • Weapons damage: +5% - plasma lance only
690 seconds Being the last update, it considerably increases the offensive capacity of players.

Overall, Thel 'Vadamee is a leader which needs to engage his enemy constantly. Lacking static defenses, a common issue when playing Covenants, Thel's offensive bonuses grants that the enemy will focus on defending his worlds, rather than attacking the other ones. Be careful however, since the Covenant's industrial base is weaker than UNSC's one and so it is not suitable for rebuilding from scratch entire fleets quickly.

As all leaders, he has access to unique ships, namely:

  • PCS-class fireship, a vessel that is armed with an incredible amount of plasma lances. What the PCS lacks in vitality it more than makes up for in speed and sheer damage potential;
  • RPV-class light destroyer, a lighter and more nimble alternative to the CPV-class heavy destroyer. Equipped with a small fighter complement, Supreme Commander 'Vadamee uses these vessels to great effect in chasing down enemy warships and harassing enemy capital vessels. While fast, they are fragile;
  • DAS-class storm cutter. Fast, but small and incredibly fragile, the DAS supports Thel’s fleets with anti-fighter interdiction and first strike raiding capabilities;
  • Kerel-pattern assault carrier, the absolute embodiement of Thels' tactics, focusing on high mobility and overwhelming firepower, assisting against his campagin against the humans.

High Prophet of Regret[]

Regret stands as the most well rounded leader in the Covenant roster, focusing on improving both militarily and economically with Forerunner technology being appropriated for use in his fleets. He is technically a jack-of-all-trades, since he doesn't focus on a particularly field. Much more flexible than the other two Covenant leaders, capital ships and carriers are at the centre of any strategies with him.

Name Improvements Upgrade time Description
Divine directives
  • Tax income rate: +1.5 - capital ships only
  • Max shield points: +10%
276 seconds Increase tax income rate for capital ships and shield points for all ships.

The Great Journey Nears
  • Max allegiance: +5%
  • Max provisions: +15%
552 seconds Regret cannot be defeated via loss of planets as long as he retains at least one capital ship. In addition, maximum allegiance for all planets is increases, alongside maximum provision for all ships.
An Anodyne Spirit
  • Capital ship crews: +2
  • Max trainable bonus level: +1
  • Orbital logistics capacity: +1
690 seconds Being the last upgrade possible, it considerably increases Regret's number of capital ships deployable and the trainable level of their crews. Also increase orbital logistics capacity.

Overall Regret has a vast number of strategies he can play with. However some he has some bastion, such as improving the economy and the heavy use of capital ships. He is the most flexible Covenant leader.

As all leaders, he has access to unique ships, namely:

  • the OAS-class assault carrier/Syfon-pattern CAS-class. Regret’s assault carriers lack the incredible firepower and robustness seen in the titan of previous releases, but feature a number of supportive abilities that make it far better than the run of the line CAS-class;
  • the DSC-class support ship, a smaller vessel that supports the fleet with modest support abilities and carrying capability. In general, what the DSC lacks in offensive potential on its own, it makes up for in its ability to improve whatever fleet it finds itself attached to.

Imperial Admiral Xytan ‘Jar Wattinree[]

As an explorer and guardian of Covenant space, the legendary commander Xytan specializes in strong logistics and adaptability while having access to ships mostly unutilized by the rest of the Covenant. Being the opposite of 'Vadamee, its strategies are based on slow but steady expansions, having slow but resilient vessels and powerful defense technologies.

Name Improvements Upgrade time Description
Protective fervor
  • Orbital defense capacity: +4
  • Bombing damage taken: -20%
  • Price: -25% - tactical capacity planet upgrade only
278 seconds Improves planets' capacity to resist an orbital bombardment and also decreases costs for every tactical defense building.
Imperial Admiral's Zeal
  • Max hull points: +10%
  • Armor points: +4.0 - while in owned gravity wells only
414 seconds Gains for free a DRA-class utility vessel whenever a planet is colonized. Also increases maximum hull points for all ships and the armor points as well - the latter only when in owned gravity wells.
Shore up the defenses
  • Orbital defense capacity: +4
  • Max upgrade count: +2 - starbases only
552 seconds Increases starbases' maximum upgrade capacity and all planets gain additional defense capacity.
Defender of the fringe
  • Chance to replace: +10% - frigates only
  • Slipspace jump detection out to two jump
690 seconds Being the last upgrade possible, Xytan improves its capacity to protect Covenant space by detecting slipspace jumps out of two of them. He also gives a chance to replace for free frigates when they are destroyed at the capital planet.

In a similar way to UNSC leaders, Xytan is the opposite of 'Vadamee. However the lacking of defense for the Covenant as a whole is a problem that can be mitigated by unique ships Xytan has access, which are:

  • ADP-class escort, a slow but well armed escort against both enemy fighter crafts and warships. What the vessel lacks in dexterity it more than makes up for in defensive capabilities;
  • RCS-class armored cruiser, an older relative to the universally known CCS-class, it supports Xytan’s fleets with a very powerful taunt ability that pulls enemy fire towards it. While useful, the vessel’s age gives it sub-par weaponry and shielding for its size;
  • CDA-class battlestation, a mobile refit and repair station that is now relegated to Xytans fringe defense fleets.

While these are slow, they are also so resilient and versatile, and they can assume a wide range of role in a fleet. It must be noted that advancing with Xytan in enemy territory is much slower than 'Vadamee or Regret, seeing its defensive-based strategy.
