Tb fireball 1350
incorrect, you can only do a 1350 fireball if you get full points into deep freeze and get the fire and ice ability, clearly mines are better than fireball per points invested(4 to 9). that isnt even factoring in the slow effect either.
Rook hammer 1700
correct me if im wrong but i think damage is split when there are more characters around, e.g. if you use the hammer over an entire creep wave you do 1700/number of creeps and demigods.
Ub spit 1600
this does 150 initial damage, and 1500 over 10 seconds at lvl 4, putrid flow does 500 damage over 5 seconds aswell if you put another point into it.
its 5 skill points down
mines is actually only 4 points
