    • Mid Boss HP is now fixed at the spawn time. Base HP increased from 6725 to 12500 and growth reduced from 470 to 200.
    • Reworked Rejuv reward from Mid Boss. No longer buffs troopers, reduces respawn time and buffs various stats. Upon death, 3 rejuv crystals fall to the ground (4 for subsequent midboss kills). Claiming one now grants you in place revive after 3s. If you already claimed one and claim another, it'll go to an ally (priority is closest allies first, then most recent dead allies). Dying with Rejuv no longer counts as a kill/death nor gives out bounties. While you have the Rejuv buff, you gain the following: +20% Max HP, +20% Fire Rate, and +15% Spirit Damage. Gaining the buff heals you to full and lasts up to 7 minutes.
    • Rejuv buff duration reduced from 7 minutes to 5 minutes
    • Rejuv now drops 1 crystal again, with each heavy melee hit granting a credit to the team (up to 3 for first midboss, and 4 for subsequent ones). Everyone on the team gains the buff. Whenever an ally dies, they respawn in place, lose the buff and your team rejuv credits get reduced by 1 (an ally can only consume one rejuv credit). The top bar has a UI indicator for how many rejuv credits remain. When all rejuv credits are used, the buff disappears for everyone.
