hello, so I ended up just doing a full reinstall of the base game and mods. which has fixed the problem. I have no idea what caused it thought. I last played in 2023, but I used the most recent version of the game from GOG and the linked mods. I am using windows 11. than you for asking
1) [not a bug: see update below] Cloak of Arachnida : the Help section of the game says it procures Freedom of Movement, immunity to poisons, and Web spell once a day. It only does Web once/day, whether I craft it or spawn it. I see no buffs icons and Entangle or Web affects the wearer. I have not tested poison, but the lack of buffs icons is not promising. I tried resting 8 hours while wearing it. In protos.tab, it does though say "Ring of freedom of movement" (params set to 0) and "Proof against Poison" (param set to 2). UPDATE/EDIT: it turns out that a character wearing the cloak can indeed move freely in Entangle, Web, etc. Poison does not seem to work either (not enough testing, but). In fact TemplePlus (DM Mode) allowed me to see the character is considered as wearing a "Ring of freedom of movement" and "Proof against Poison". So the problem is a) the debuffs are shown as if they are Webbed, Entangled, Poisoned, etc., even if they are actually not, and b) the buffs are not shown. The actual Ring of Freedom of Movement, for example, also does not show any buff icon: so I guess that is normal. But a Potion of Neutralize Poison does show an icon (I wonder if a duration would trigger showing an icon). I tried showing icons for fun: no success up to now. __ 2) Vanilla Spellcraft +2 Synergy bonus for Use Magic Device with scrolls : not working. In comparison, the Bluff Snergy bonus (to other skills) does work. __ 3) the area-of-effect shown for Entangle is clearly smaller than its actual area-of-effet. I am often affected when standing about 5 to 10 feet away from the green circle.
https://github.com/GrognardsFromHell/TemplePlus/wiki/New-Indicators From what I understand, indicators / effect icons (buffs, ailments, conditions) are only shown for spell effects or status effects with a duration. When you’re wearing that cloak, no spell is actually being cast, so no indicator is displayed. By contrast, a Potion of Neutralize Poison does show an indicator on the character portrait because, under the hood, drinking a potion is equivalent to casting a spell of the same type as the potion.
Sure looks that way (that item effects were not included, presumably because they could not). Thanks. My point #1 is clearly not a bug (more like a feature request for TemplePlus) and the cloak works.
