Did the essential mods in said post by bluejays2025 and it worked fantastically.

Been doing a solo run and just got ot the TOB part of the game. I was hoping access to the level 10 mage spells would open up in TOB as maybe some limiter was put in place during the whole mod process but no such luck. I'm a Fighter/Mage/Thief and 25+ levels with each class respecitvely. I have access to every special uber power per class except for those spells, i.e. planetar, dragon breath, alacrity(or something like that) and maybe one or two more of those spells.

Where are they? Was hoping for some Planetar fun :(

IIRC, they go in the same list in your mage spellbook as the Lvl-9 spells. So they may be right there if you've selected them upon level-up, but you were looking in the wrong place.

Failing that, I'm not at sure where they may be. Hopefully someone w/more mod experience will be able to help.

Sorry guys name was GoJays2025 AND I am aware that after the spell is chosen from the abilities list it shows as a level 9. I don't get said spells in my abilities list to choose from after leveling...

Generally, triple classes don't get mage HLAs because of the XP cap, but seeing as you have level 25 in each...

You should start getting mage (and other) HLAs @ 3,000,000 XP. In the unmodded game, you get HLAs before you cast mage level 9 spells, and so don't get access to the 10s.

What mods do you have installed?

BG2 fixpack makes mage HLAs "Extra 6/7/8 Level spell" available to F/M/T.

Did you install the BG2 Tweak Pack component "Triple class HLA tables"?
