When I tried to use Fall of Heaven (as in, really activate it after charging), the animation stopped at some point and the whole screen just flashed brightly. I waited about two minutes to see if the animation was just extremely long, but apparently that was a bug.
Adapt and Revenge are really powerful together. I currently have almost 138 million click power, enough to completely glitch the game and buy tens of minutes of time. There's nothing I cannot buy in a few clicks, if more than one at all..
I have no idea how to complete the challenge on level five in the third campaign. While I do understand that it becomes considerably easier while using the Stopwatch, the challenge still is equal to "get hit a maximum of one time" even before the paradox.
I'd like to see Blacksmithing giving Str (instead of Int?), it would make more sense in my opinion. Also, there's only one skill that I know (yet) which gives strength, which is another reason why I'd like to see that.
Healing SPELLS can't be cast outside of battle, yeah, but healing POTIONS can be used... so why are you complaining? :(
By the way, is actually pretty easy without a cleric. Get a INT Ranger, use a Conjuror with Healsprite, use HP Regen equip, use an offensive team so the enemy dies before able to inflict 'real' damage...
I recommend NOT getting the Final Blow skills. They slow down the final strike of your combo, reducing your combo ability against some enemies and disabling your ability to kill a dead enemy again sometimes (for example, one-hitting a slime and hitting it again brings another kill for the same slime). This reduces your HP/SP Regen upon kills.
