Titan Host is a legendary major card out of the New mechanic pool. Spirit Host raises one titan for 30 s at 250% damage whose bite splashes 2.4 u.

You can take it once · it only turns up when your Ultimate ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Legion and Martyr Host. Take one and the rest are gone for the run.
