Attacks & Counters

Attack Counter
Acid Spit: This attack is predictable due to the Thresher Maw's animation movement before spitting, but the spit still travels fast and it could be hard to avoid. Find cover on the columns but be aware that Thresher Maw may destroy the columns with a few spits, so always have in mind another place to cover quickly in case that happens. The last two columns cannot be destroyed.
