+* Tower Ideas
+
+3-4 total towers. Two of which actually do damage? 3-4 abilities per tower, no "tiers of upgrades", each can be bought at any time in any order, but only up to 2.
+
+** Warlock
+
+Basic shooty tower
+
+** Wyvern
+
+This would be the main AOE tower, but also possesses lots of pierce:
+
+- Default attack: a short range spray of fire, which doesn't fire straight. Med damage, infinite pierce. Has to 'warm up' for a second
+- Forked tongue: an upgrade that replaces the single jet spray with two jet sprays, however none of them are directly where the tower is aiming
+- Ice dragon: replaces the fire attack with ice, which has low damage but slows. Forked tongue combined with this would work the same
+- Lightning dragon: replaces the first attack with a fast, immediate lightning strike. High damage. Forked tongue works the same, but combined with ice dragon, changes the attack to a slow-firing icicle with infinite range and pierce, high damage and slows. Tower becomes long range.
+
+** Werewolf
+
+Charges down the path (not around corners). Grabs the first enemy it collides with, dragging it back (moderate speed) to its original tower position, dealing damage the whole way. If the enemy is still alive when it finishes, it releases the enemy there. If the enemy dies midway, the werewolf charges back to its original position.
+
+This tower is meant to be slow, but high-single target damage.
+
+Obviously, the werewolf will be ineffective if placed on short straights, but very effective if it grabs a boss enemy on a long straight (anything it grabs is probably dead...)
+
+Enemies in another werewolf's grasp cannot be grabbed, but using multiple werewolfs on the same path may still be interesting.
+
+** Wellspring
