Cripple MOAB/Strategies

A good strategy for this upgrade is to set it to priority strongest, allowing it to always target a MOAB class bloon if there is one on the screen, so that more MOAB-Class Bloons get immobilized. Also, setting multiple of these to different firing speeds will help (from upgrades or a Monkey Village). Use this tower as support and not a primary defender. It is much better suited for later levels, where MOAB class bloons actually appear.
