Demi-Phoenix “Summoning Sickness”
When Demi-Phoenix manifests it cannot react immediately to an action after being summoned to proc Scarlet Flame.
It is believed that this is due to the 0.6s of animation lock attached to Everlasting Flight.
Repeated Egi Actions (5.10)
With the advent of Patch 5.10, Melee Egi Summons could find themselves stuck in a perpetual loop of using Egi Assault II over and over while in active combat but missing a target. Each use of these spammed actions would generate a Further Ruin stack.
The Egis were also able to repeatedly spam Devotion under certain conditions, while also repeatedly using their Enkindles for additional damage.
This has since been fixed as of the 5.10 Emergency Maintenance on October 31st.
Demi-Bahamut “Summoning Sickness” (5.00)
When Demi-Bahamut manifests, previously in Stormblood Demi-Bahamut would react immediately to an action after being summoned to proc Wyrmwave.
As of Shadowbringers Demi-Bahamut has a brief window after he manifests where he cannot react to inputs at all, a term some of us have dubbed “summoning sickness”.
This has since been fixed as of patch 5.10
Infinite Devotion (5.00)
Early Shadowbringers release it was possible to reset Aetherpact’s cooldown with a particular Egi action input sequence, resulting in full uptime of Devotion.
This has since been fixed as of Patch 5.01.
Further Ruin status not refreshing (4.0)
Previously if you had a Further Ruin proc while you already had the status it did not get refreshed to 30s. A bug report had been submitted about it, this problem made it tricky to know for sure how many procs we actually had in a given run.
This has since been fixed as of patch 4.4.
