This thread is about the various abilities with their effects and their impact on balance. Many abilities in the game work in the weird way, partially because they are not implemented properly yet. I will go through the abilities and talk about those that catch my attention. Since I have not played all classes, I can't give feedback on everything, so some more reviews would be appreciated.
Engineer/Bomb: If you ask me, this skill is just too plain powerful. I think the damage should be calculated similar to summons - No matter how many enemies there are, always do the same damage. This would make the engineer a bit less overpowered against single bosses, but good against multiple enemies.
General Buff Evasion: I think that all buff resistances of the normal classes should be reduced to 0, meaning that the buff will always hit when used on a single target and sometimes fail when used on multiple targets.
Blink: Blink should only give a 50% or 75% evasion chance. Immunity against physical attacks will result in physical attacks being underpowered, which will in turn lead to bosses relying on "special" attacks for balance.
Cover: This seems quite useless(because of Blink and the general fact that endgame bosses don't use physical nukes). Have this work on area damage like Bluster at least.
Drain: Overpowered on bosses, useless on encounters. Add a component that is based on your wisdom, not only on your enemy's HP. Maybe raise the damage cap with the level.
Sylph: Similar to Drain, raising the damage cap with the level may make sense.
Phoenix: owtf? Cap at 3k HP for reviving or something.
Summons in general: May make sense to limit their amount of uses in battle. This would make it possible to make summons a lot more powerful than normal spells(thus making the wait time for the animations worthwhile), yet you would only be able to use them a few times, so you would have to rely on other magic for the bulk of the battle. It would also make the less powerful summons more useful.
Death: Make it true death.
Pierce: This is so useless. Just Jump with more damage. Maybe give it a damage type, effect or multitarget instead.
Remember: Use real spells from the white/black school. This is WIP.
Mana Heal/Prayer: These are in the way of my plans to have battles where you can't use items. Usually, you would have to play carefully, preserving your mana, but these classes can just restore them with a snap! Must think of something..
Dance: It feels.. not that great for being a ++ class's trump.
I can't think of more right now. Feedback is welcome.
