Is there any issues stacking these 3 spells, say a level 17 wizard casting Time Stop, then casting Greater Angelic Aspect & Legendary Proportions, then lastly casting Transformation(could Contingent spell this) to come out of Time Stop as a badass angel of destruction basically.
Transformation
School: transmutation; Level sorcerer/wizard 6
+4 enhancement bonus to Strength, Dexterity, and Constitution.
+4 natural armor bonus to AC
+5 competence bonus on Fortitude saves, proficiency with all simple and martial weapons.
Base attack bonus equals your character level(including adding additional attacks).
You lose your spellcasting ability, use spell activation or spell completion magic items.Legendary Proportions
School transmutation; Level sorcerer/wizard 7
+6 size bonus to Strength
+4 size bonus to Constitution
+6 size bonus to natural armor
10/adamantine DR.
Carrying capacity changes to reflect its new size. The creature’s equipment and weapons(including ammunition & thrown weapons), if any, also increase in size.Greater Angelic Aspect
School transmutation[Good]; Level sorcerer/wizard 8
low-light vision
darkvision 60ft
DR 10/evil
immunity to acid, cold, and petrification
resistance to electricity and fire 10
+4 racial bonus on saves against poison
Fly 60ft good maneuverability
Truespeech
Protective aura: +4 deflection bonus to AC & +4 resistance bonus on saving throws against attacks made or effects created by evil creatures to anyone within 20 feet. Otherwise, it functions as a magic circle against evil and a lesser globe of invulnerability, both with a radius of 20 feet.
Mind you, none of these spells are of the polymorph subschool, & only one increases your size so no stacking issue there.
Best Answer
There are no stacking issues between those spells. None are polymorph spells so they don't override each other. All the bonuses are typed differently so they'll stack.
Now, if you're asking if it could be too strong, that's a different story. The three together can make a wizard half decent as a frontliner, but it still won't be good. Take the normal wizard with 10 strength. You end up with 20 strength, full base attack bonus, no feats to help you, and +14 AC (compare to a fighter with +5 Full Plate, who also has his own other bonuses). All in all, you'll still be outshone by a fighter doing his thing, and you won't be able to use your spells (and you blow 3+ high-level spells trying to set it up).
