Evil religious background

This background offers mainly front-row guilds that combine melee and spellcasting.

Reavers

RoleMelee, focused on offense
DescriptionGuild thematically built around destruction. Has fairly good melee offskills, as well as WIS-based blasts. Training most skills is locked behind their energy bar - the good skills require getting to the 3rd layer. If you have no energy, reincarnating into the guild can take a while, as you need to build it up to be able to train many skills.
WeaponsPolearms, axes
Important skillsReaver strike, Way of the scythe
Important spellsWord of spite, Word of blasting
Rep/questsKilling mobs gives destructive energy that allows training better skills. Using word of spite improves damage against mobs of that race. A variety of quests, generally focused on destroying various things, gives some bonuses.
Other considerationsReincing into the guild takes a while if you have no energy. If you do not use any offensive reaver skill for a couple days, you start losing energy. As such, this guild isn't very suitable if you plan to play infrequently.

Tigers

RoleMelee, focused on offense
DescriptionTigers are a bit of an oddity - they are an assassin guild in a PvE-oriented game (although at the time of writing this, their assassination missions are disabled). Similar to monks, they are a martial arts guild, but in addition offer the Tiger claw spell, whose stunning effect is useful in experience parties. They also get lock picking and stealth skills.
WeaponsMartial arts
Important skillsDim mak
Important spellsTiger claw

Disciples of Chaos

RoleMelee, focused on offense
DescriptionDisciples are a 10-level guild that allows you to transform into a chaotic spawn, which gives a fairly good attack, improves stats, and adds tentacles that do damage and can wear rings. The guild is not meant to be taken as a stand-alone one,
WeaponsDepends on the chosen followup guild.
Important skillsChaotic spawn, Clawed strike, Choreography of mutilation
Rep/questsKilling mobs in spawned form improves the spawn, increasing stat bonuses and tentacle count.
Other considerationsExperience gain is reduced substantially while in spawn form. This is a base pre-requisite guild for Tzarakk, Kharim, and Aelena. If you do not plan to join one of those, joining disciples is generally not recommended.

Evil Priests

RoleBlaster
DescriptionBack-row blaster guild, its main advantage is that its harming spells cannot be resisted (although some mobs are immune anyway). The disadvantages are that the spell has a rather poor spellcost/benefit ratio, the guild offers nothing else and gets boring fast.
Important skillsCast harm, Mastery of pain
Important spellsHarm body, Aura of hate
Rep/questsNone
Other considerationsIt is common to take some priest levels for healing spells, aura of hate, and cardiac stimulation. Full priests are rare, however.
