ToME: the Tales of Maj'Eyal

Revelation from the Demented/Doom tree does not seem to have any affect when applied to Prophecy of Madness or Prophecy of Treason. in a video i posted in the discord (or just take the anecdotal evidence), it shows that a target affected by prophecy of madness (just take my word for it that i triple checked that i had revelation applied to PoM) used a talent, but neither of the two talents i had on cooldown were affected. 3/5 revelation, CD reduction should be 3, though the fact that there was no reduction at all aside from the single turn passing speaks for itself.

I later stuck prophecy of treason on a target with revelation applied to it (made sure the prophecy was successfully applied and was still applied after the next turn) and then took damage on the following turn. not sure if any of the damage i took was reduced in any way, but no damage was redirected to the affected target (game log shows no attempt at redirecting, enemy hp remained static). its worth noting that the treason description for revelation mentions the damage will be redirected to "a random target affected by the damage link", and its really not clear what the damage link referred to is (id imagine its just referring to the prophecy itself, though the implication that it could be multiple targets affected is confusing??). overall not ruling it out that im misunderstanding something, but overall appears to be nonfunctional as i tested.

the good news is revelation is working just fine on prophecy of ruin. damage done, health regained.

I'm having this problem too. I have been using Revelation w/ PoM on my
current run and have yet to see it trigger.

Under 1.6, when this effect triggers, there is also a message in the log.
Unless that has changed too, you don't have to mouse around, just check the log.
