OK, here we go then.
It will apply to :
- All food including Hylea's Boon
- All resting place at inns
- Prostitute Bonus
I'm not going to track down every unique one-time Bonuses until next rest, but feel free to complete the list above if I'm missing something important (repeatable) and relevant.
OK so after my testing it seems that there's something intresically degenerate with using several abilities that grant + duration.
After 1 kill while in Fury form, every single BPM version Salvation of Time tick (which grant +0,5s every 1s) granted about +4-5s duration.
I've not spotted anything weird when a single effect is used.
It seems to apply to everything using + duration (BPM Bloodstorm, which has a different coding as Fury bonus duration on Kill).
Ahem
Impossible to correct something broken by hardcode apart by removing the +duration effects...
So my point of view is to fix the most degenerate cases.
1) I won't change BPM SoT because it is nice. I would recommand not abusing it with abilities with +Duration effect.
BPM SoT and Wall of Draining seem to interact fine.
2) I want to keep Wildstrike Frenzy as it is. It is the corner stone of SC Druid balance.
3) There's a couple of self-prolonging abilities around : Blood Storm, Pain Persists, Each Kills fed his Fury. Honnestly, I don't believe they would be "too broken" if a glitch allows them to prolonge indefinitely.
4) Fury is the main issue IMHO.
- BPM added a +10% damages on Kill in Blight Form until the end of the Shift (stackable 3 times). This one would be broken to prolonge indefinitely.
- SC Fury intresically gets an ability (the shift) that has 2 means of prolonging. This is the only case (I think) when an ability is broken on its own, without any combo. Since it is hard coded, there is basically no way to fix it (unless I'm missing something).
=> My proposal is to cut Fury duration extension on Kill. Because of point 2), it would affect less the game than cutting Wildstrike Frenzy duration extension.
=> I will also change the +10% damages on Kill in Blight Form until the end of the Shift to +10% damages on Kill in Blight Form for 30s (INT and PL apply). The effect will be limited in time independantly from Shifting duration BUT will last after the shift. This will keep the spirit of "Fury getting additional benefits from Kills in Blight form" even if I have to abandon the virtuous circle of getting more damages and duration per Kill (so more duration of more damages etc...).
I haven't been able to reproduce this on my game (tested with melee and ranged weapons), and I haven't spotten anything weird in the code either. So I have no mean to address this.
If it really fails on your PC, just check the load order as BPM should be loaded after CP. And if it fails, then sorry, but I'll recommand to delete this particular change and go back to CP version of backstab (which is quite fine too).
