Bishop Leonid

Information
Fought in tandem with Bishop Alexei, the third boss is fought in the Gysahl Catacombs after finding Gysahl's mayor in the Fire Shrine. They have great synergy with each other, and are notably a difficult and chaotic fight. Leonid focuses on physical damage and supporting Alexei's spell preparation, as well as dragging him along for his Blizzard and Thunderstorm spells to be much more dangerous. Unlike Richter and Cain, they have no access to any buffs or debuffs. Leonid's most notable attacks include Speed, binding Alexei to himself, arrow spam, and Conductivity, which is very dangerous as it is paired with Alexei's Plague. Inflicting Freeze on Leonid can be extremely useful, so spells like Blizzard are recommended. Blizzard has the additional usage of being a 6 hit spell, which can break both Leonid and Alexei's protection/Plague charge stances. However, once Alexei falls, Leonid will prepare Ultimate Sacrifice. This spell can not be dodged or survived, so you will need to kill him before it is casted. Likewise, if Leonid falls before Alexei, he will do the same.
