MonolithIce

Description
The Monolith doesn't change it's attack pattern. It only changes how much health it has.

Strategy
The Ice pillars don't disappear before the Monolith shoots again, so unlike with the Ice Launcher, the Monolith will start filling up the player's grid fairly fast. Spells that fire shots forward are helpful at destroying the Ice pillars, like.

The Monolith has a short chargeup before shooting, so the player can destroy it before it becomes a threat.
