Quick Question About Devotion Abilities

[David McMurdo]

When you complete a constellation and are given some ability, you are asked to attach it to a skill you have. Does this have any bearing on how it triggers, or is it just a way of ensuring that players don't become overpowered through devotions? For example, if I access an ability that has a 10% chance of triggering when I attack, but then attach it to a healing skill, will it trigger less than if it were attached to, say, my primary attack skill?

Each one shows you what skills in your masteries you can attach it to so I doubt you'd be able to attach it to a healing one. And yes, they must be attached to proc.

Specific devotions can only be attached to specific categories of spells, so as Medea said, it won't allow you. If devotion skill binds to passive buff, it usually cannot be assigned to attack or vice versa. Devotions that summon or buff pets, cannot be assigned to pets, etc.

But the chance can sometimes change depending on skill you attach it to. For example, on my current character, I have Flame Torrent skill from FIend devotion, when I attach it to Leap from movement rune, it has 100% chance to trigger, but if I attach it to Guardian of Empyrion, chance goes down to 25%.

Sometimes you simply have to experiment a bit to see what feels/works the best. You also might need to do some tradeoffs, some devotion skills might be less important than the others, for example in my case, Eldritch Fire devotion is more important than aforementioned Fiend, so I will try to maximize the uptime for it, even if it means that means Fiend will trigger less often.

One thing a bit offtopic, but still worth noting regarding this topic is that even when the skill deals 0 damage, it can still crit and trigger on-crit devotion.

I have the aether and lightning floor hazards attached to my pets (the summon spell) and they trigger all the time (from the pets attacking). The skills also seems to level up from the general xp you get, I noticed this when one leveled up while I turned in a quest.

More clarification.
- A devotion skill will only trigger off of the skill it is bound to. If you put Falcon's Falcon Swoop on Soldier's Blade Arc, only blade arc will trigger it.
- Devotions that bind to Auras or other PASSIVE abilities will trigger as long as that ability is currently active. Example: if you bind Tortoise's Turtle Shell to Nightblade's Pheumatic Burst, you can only trigger the Tutle shell buff while PB is active. But if you bind it to Nightblade's Veil of Shadow, it can always trigger as that aura is fully passive.
- The trigger rate of a devotion skill will improve if the skill it is bound to has a cooldown. The higher the cooldown, the more the trigger rate will improve. There's some balancing to be done on your part for if you want the skill to trigger more reliably (or even 100%), but only when you use a skill with a long cooldown.
- If a character skill hits many times (like Demolitionist's Blackwater Cocktail or Inquisitor's Word of Pain), then a devotion will attempt to trigger on EVERY hit on EVERY enemy limited only by the devotion skill's own cooldown. This means that devotion skills with low or nonexistent cooldowns (like Imp's Aetherfire at 0 sec or Fiend's Flame Torrent at 0.5 sec) can trigger rapidly across large groups if bound to an AoE multi-hit skill.
