Hi, thought I would like to offer some feedback about taking the beta version from December 2016 through BG 1 and SoD.
I love most the changes and new spells, especially True Strike (for my bard), but also the new summons, especially the shadows.
Bugs I encountered:
Several incorrect strings (modmerge was used correctly, other mods were fine), including: name of familiar item in backpack (description was ok), summoned creatures from new spells (e.g. shadows and serpents) and when mages prebuffed with some of the new spells in the log
With revised SCS (probably a bug there instead) and only long-lasting pre-buffs, enemy spellcaster still start short duration summon spells at the start of combat (Summon Monster, mostly slimes)
Not sure if it was SR, but the ghost of the bard on the first outdoor SoD map (the menhir quest), is supposed to vanish the end by casting some sort of spell. With SR he cast shapeshift: spirit troll instead and remained on the map (non-hostile, looking normal, not like a spirit troll)
Changes I did not like:
Haste. It was always party-wide in any D&D game. It is also the counter to slow, which is also an AoE. Really dislike it being single-target.
I miss the old clairvoyance, which I liked to use to see the entire map.
Also, I miss having access to a spell that lower spell resistance a bit at or before Level 5.
Also some thoughts of the changes to True Sight, ND and Improved Invisiblity: not played BG 2 but followed the discussion. As it is, this will be quite a nerf to Edwin and Conjurers in general, as they are barred from True Sight and will not be able to dispell spell protections from a protected mage. I know there are items that cast True Sight for you (Gem of Seeing and Book of Infinite Spells with luck), so there are workarounds, but still. Have you considered making True Sight castable on party members?
Have not decided yet, but I will probably not take it into BG 2 right now, due to the monster summoning thing at combat start (I do not want to fight Greater Basilisk whenever I fight a high-level mage) and the true-sight thing. Maybe I will have a stab at changing these in my installation instead.
Thanks for making this mod. Once it is a bit more stable, it will probably be part of my standard installation.
