Earth Mastery
The two aren't really all that comparable. For more damage, fireball is what you want. Stalagmites would be useful if you had another stun to stack it with, but on elec/SS, you don't. The damage is worse, the animation is slower (IIRC), and the stun would only work on minions (which you probably don't need help on). And unfortunately, they both require the same amount of power choices.
Looking at the other choices, you won't get the ST attack that fire mastery has, which may or may not matter--you'll instead get a slow patch and/or sleep attack.
So it comes down what would be useful set bonus wise, and/or variety/damage.
thx stone for the info

Could some one help me out thinking of taking earth master over pyre for my elec/ss tank just curious of how stalagmites compares to fireball and if earth master is even worth taking as a change of pace thanks for the info.
