Yes, but sometimes that limited range is a good thing for one, pylon levels and in endurance, to prevent your damage gem from killing everything before it reaches you mana farm. So damage gems in towers is still far more effective until you reach the point when your trap can deal over 10 trillion damage per shot. A tower will likely reach over the entire screen by this point. > Because you have to remember, while an L/Y in a trap will do more damage than an L/Y in a tower, that trap only hits the square it’s on and a little away from it. It’s not much when you’ve got a dozen or so hits and even less than a hundred mana per hit, but as you get to higher grades… Spend the rest of your money as follows: Build your trap, your trap amps, and the appropriate gems. Since the Freeze CD got nerfed, its pretty difficult to get thousands of monsters clumped on top of a farm. Do you use y/l/o, or just y/l? Because in my experiences, it’s not so much the lime that causes loads of lag, but the lime _with_ the orange, since, on higher grades, the game has to, for each of the hundreds (thousands) of hits, take the mana gain, multiply it by the mana multiplier, add it to mana pool, and possibly extend the mana pool, maybe many times. Enrage levels 1-6 with 12 level 1 gems each. Blue in farm gems makes it easier to pile monsters up above a longer mana farm. Hm… yeah, I guess towers might be less laggy. For composition, I recommend an L/O/C starting with 5 G1 Limes, 5 G1 Cyans, and 6 G1 Oranges and merging them all into a G5, then upgrading as I can.

Now, as for my mana farm, I’ll usually place the trap as close to the spawn as possible while giving it as many amps as possible (max of 6, since the monsters have to get to/get off the trap or else it blocks the path/makes the trap a useless dead end that the monsters never walk on). Because you have to remember, while an L/Y in a trap will do more damage than an L/Y in a tower, that trap only hits the square it’s on and a little away from it.

> At a certain point, L/Y becomes far more effective in a trap than in towers.
