One thing my Sorceress was aiming for in the devotion tree was a spell called "Tsunami". You can get it right away, near the beginning of the game. It doesn't do much damage, but it was listed as "100% on Attack", meaning it would trigger constant with whatever spell I assigned it to.
So I finally got the shrine last night that allowed me to get Tsunami. I assigned it to Great Fireball, since that is my left click skill. It was glorious. Each explosion of fire was accompanied by a little refreshing shower for each enemy (no, Tsunami is not an appropriate name for such a mild visual effect). It was great though, why not add some cold damage to each fireball that I'm constantly doing?
And then a few minutes later something changed. The little refreshing shower each fireballed enemy was getting was rarely there. Is it because the fireball was killing them? That wasn't stopping the shower earlier. So I checked the devotion tree again, and this time it said "Tsunami (35% on Attack)". What a horrible bait and switch. I looked online, and wikis always listed Tsunami at 35%, but in the game itself on the tree it was 100%, and it acted like it in the beginning too.
Now I wonder if other things on the Devotion tree are also bullshit. There's a "Cleansing Water" spell that I was thinking of going for that is also supposedly 100% on attack. And it basically is a dispel magic spell. It dispels any beneficial effects on enemies and harmful effects on you and allies. That sounds pretty cool at 100% on Attack. But if I finally get there, and after a few minutes it turns into 50% or something, I'm going to be pissed.
