Silver Raven

Nalia ring aswell (couldn't confirm , not in my party, but she has an unremovable ring)

U can delete all the spells u think u'll never use...but don't touch spells that some monsters casts...it's messy job but the spells deleted directly don't appear any more.

which ones ?

so far i only removed earthquake (a piece of crap imho)
but when the cleric lvl up & rested she got the spell back (for info earthquake is used by one type of monster in SoS, deletion didn't prevent to get the spell back)

i understand why there's the ranger-cleric glove now in BP, whish pure cleric can use them.

You could use SK and delete some spells you know you dont use then load your game and level up.

ronin

k i tried this, but unfortunatly the game gives me back the spell i removed

was max lvl 7 spells, removed 1 with SK
then lvlup at lvl24 picked up one new HLA and rest
after i rested the game gave me back the spell i removed previously and so pushed out of the page the last spell writen at the bottom right.
and yes the spell pushed out is still present in the spells list , but not accessible from the book

although if edit the save game after lvled up, that's works, i believe i will need to do this every lvl the cleric will gain

erm
Imoen doesn't have her belt after the Asylum (well that happened to me)

unremovable item not given back (those from my party members)
-Edwin's Amullet -> MISC89
-Abyssina's Necklace (Valygar necklace) -> VALNECK1

well i edited my savegame with SK to get them back.

no clue.
as far i know each time u gain a priest lvl u get all spells regardless this lvl and as i saw tdd adds some spells the cleric / druid / ranger the first time they lvl up (depends the ranger's wisdom though, if u look at Minsc, eh, he won't get any spell at his first lvl up ), The idea , although would be convinient.

number of priest lvl7 spells + tdd spells = 14 , yikes, that let 2 slots for quests spells ....
