Hieronymus



Hieronymus is a Raid boss in Blue Archive.

Hieronymus is a single entity boss fight who can be focused down with strong single target damage dealers. However, healers must be brought to this fight to engage with the Relics to get past Hieronymus's naturally high DEF and Damage Reductions. The fight itself may be considered simple, but the challenge in Hieronymus is being able to build a team which is capable of sustaining both continuous damage and continuous healing.

Stats
The following table shows the HP of Hieronymus's holy lantern relics for each difficulty: The green/red lantern is classified as an ally, and starts at 5% health. It has 500 DEF (Normal~Extreme) or 2,500 DEF (Insane), and may be damaged by Hieronymus's attacks.

The purple lantern is classified as an enemy, and starts at 100% health. It has 2,000 DEF, 999,999 CRIT RES and cannot be targeted by normal attacks or basic skills.

Additional Notes/Tips
After activating their respective effects at 100% HP, the relics will stay at 100% hp for 10 seconds, after which the HP will fall to 0% and the recovery rate debuff will be applied. Re-entry of the fight with another team will reset the status of the relics, and remove any green relic debuffs applied to Hieronymus. The Green Relic stacks up to five times. After reaching max stacks, the green relic will disappear from the current fight. The relic will re-appear amongst re-entry. The applied debuff will last for the entire duration of the current fight. The Red Relic cancels the cast of Hieronymus's next skill. If a skill is already in motion, it will not be cancelled. The amount of cost recovered by the success of the Red Relic is equivalent to 1 bar if you have at least 4 students on the team Hieronymus can only be put into the stagger state when his skills are successfully cancelled by the Red Relic. Unlike other bosses, it is impossible to put Hieronymus into the stagger state with weak attribute attacks. Hieronymus's ATG does not increase in the first phase of the fight. It will only start to generate in the second phase of the fight. Even when Hieronymus is in the stagger state, the ATG will continue to increase. The ATG increases at a fixed rate, such that on the cast of the 11th "Desert Pain" (which will occur at 110 seconds after the beginning of Phase 2), Hieronymus will always be ready to cast his special instant wipe attack. This special attack can be cancelled with the Red Relic. When Hieronymus begins casting this attack, the ATG bars are immediately consumed, after which the player has approximately 3 (?) seconds to activate the Red Relic before it is no longer possible to cancel it.
