Plane 4 Hotfix — Idle Xanxia Steam update #2828787

A couple of bug fix and adjustments : - All Stage 6 fights got a little balancing All Patriarch/Matriach have their special ability implemented - Plane 4 stability and travel Travel to/from Plane 4 should stop having unintended drop/encounter leak - Soul Forge and Armaments Tier 5 requires the new Stage 5 Sovereign material. Sovereign materials drop only from Stage 5 Heirs/Avatars - Dao, effects, and performance Withering Blight stacks correctly on the supplied affected saves, including after Rebirth/Reincarnation and with Death Law. Lower-plane Dao effects such as Veil, Temper and Flurry do not leak into Plane 4 waves. As usual let me know if you find any issue, thank you!
