In the default template, all The Fire Gleeok enemies have their weapon damage set to 4 when it should be set to 8. I mean really. In 2.10, the flames did a damage of 2 hearts. A damage of 4 is 1 heart, while a damage of 8 is 2 hearts.
(I should have mentioned this a while back)
[Default] Fire Gleeok Weapon Damage wrong
OK, if you say so....
