Arcane Impale

 is an upgrade in the Magic Monkey Knowledge tree. It increases Ceramic and MOAB-class damage of Arcane Spike bolts by +1. It requires 4 Magic Knowledge Points invested, Flame Jet unlocked, and a one-time purchase of 250.

Summary
Some extra damage to make it easier to handle Ceramics and MOAB-class. The +1 damage is much more significant against Ceramics, making it better against Super Ceramics.

Tips

 * Use 4-0-1 Arcane Spike. More research is needed to determine if the Path 2 crosspath is affected by this MK, but the bolts definitely are.

Trivia

 * Arcane Impale features a MOAB-class bloon being impaled in a similar style to the upgrade icon from Icicle Impale.
