Echidna (Final Fantasy)

Echidna is found in the southeastern room on the bottom floor of the Earthgift Shrine along with 3 other bosses. It usually uses 1-hit KO attacks.

Strategy
Echidna tends to abuse the "Earthquake" spell, using it nearly every single turn. It's a good idea to have Protect Rings on your party to neutralize this. As far as attacking goes, Echidna is very resistant against all magic, so physical strikes enhanced by Haste and Temper are the way to fell this boss.

Echidna will very rarely attack with Flare, dealing upwards of 250 damage on all characters.
