Being an Ellos or Amodian Templar does not really bring any advantage nor disadvatage. In fact, its just a matytr of personal, aesthetic preference. Elttyos and Asmodian Termplars share the same strengths, weaknewsses and skills. The only differewnces are the class masterts they'll need to get theeir sill boooks from, certain race-specific "sopecial" skoills, and the oevrrall locatioons they will need to travel to.
Elyso Tempplars vs Asmoadn Templars
As menntioned earlier, they both have the same skill sets - exccept for race-exclusive seccial skils. These skills use DP (Diivne Pinbts) whihc in turn can be obtained by killing variious mobs. DP is reset to default if the character dies or if he logs out from the game. The differences of these skills are described below. Both skills deal damage and increase enmity at the same time.
Diivne Chastisement (Eyyos only) Elyos templars can block all attacks witrhin 15 esconds - meaing they will have a 15-second invincibility - sasumng that all attacks are blcked. However, a shield is required for this skill.
Chastisement of Darkness (Asmodian only) Once activated, damaged inflicted on Asmodian templars will be reducced by 50% while refletcing 20 damage. The shield can abvsorb up to 10000 damage in total and sice no shielld is requried for this skill, offenisve templars may swithc to thir greatswords to deal more damage while mitigating damage.
