PnP Improved invisibility
I made for myself a little mod that make Improved Invisibility work as PnP 2e (i.e. as only Mislead works now) and if somebody is interested I am gladly sharing it. For those that think something like this is "overpowered" please think otherwise because mages that cast invisibility in the game (and there are a lot, especially with Shadow Door that's 1 sec cast time) can really turn your group into dust if you don't have some dispels handy (btw the mod also changes Glitterdust to force visibility in every case if a save vs spell is failed - i.e. also if you are under immunity to divination that's a sure way to remove invisibility, and you cannot after become invisible again for the duration). Hence your T/M or F/T/M becomes surely much more powerful but so it's true for the opposition.
For now the mod is just "copy to override" style. If I see that people are interested I will create a full Weidu version of it with full description changes etc.
