Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Minimum Attribute Effectiveness Spells

How many spells are there that gain you no apparent advantage (save cooldowns) of having a high intelligence beyond the minimum attribute effectiveness(MAE)?

For instance casting wildfire with 8 intelligence(MAE) is the same as casting it with a 20 intelligence mage. In my limited early game experience rain works the same way making everyone wet disregarding any checks. Are summons the same as well along with every buffing spell cast on allies? What about buffing spells cast on enemies? If my presumptions are correct I would like to make a list of these sorts of spells.

Yes on everything except DEBUFF spells on enemies, I think. Those all show a % chance to succeed based on your int.

What about buffing spells on enemies such as Immune to Burning? The wiki doesn't mention it but in game I am fairly certain I saw it lowers water resistance.

I recently did an all hybrid playthrough where most of my spells were used at, or below, the INT requirement and I found a lot of the environmental affects were still very useful. Even if the direct damage from flare wasn't great using combos to create coke points and block LoS was essential time and time again.

Like you mentioned there's several debuffs that ignore saving throws, for example rain and bitter cold is a fantastic way to freeze almost anything.

Other than reducing the cooldown, sdditional INT increases the damage of the spells and the chance of getting past saving throws.

Right but in the case of many spells there is no damage/saving throws

Sure, but that are exactly the spells you are looking for. If you prefer the explicit list:
Immune to Freezing
Wildfire
Burn My Eyes
Smokescreen
Fire Resistance Shield
Purifying Fire
Firefly
Self-Immolation
Summon Fire Elemental

Water of Life
Rain
Immune to Burning
Cleansing Water
Water Resistance Shield
Summon Ice Elemental

Bitter Cold
Farseer
Become Air
Invisibility
Immune to Electrified
Feather Drop
Air Resistance Shield
Remove Petrification
Make Invisible
Tornado
Summon Air Elemental

Midnight Oil
Bless
Fortify
Immune to Poisoning
Earth Resistance Shield
Blessed Earth
Summon Pet
Summon Pet
Summon Bloodswarm
Summon Earth Elemental

Oath Of Desecration
Unlock Magic
Absorb the Elements
Drain Willpower
Resurrect
Vampiric Touch
Soulsap
Invulnerability
Summon Undead Warrior
Summon Armoured Undead Decapitator

Spells that only get slightly worse are
Teleportation (increased falling damage doesn't matter if you teleport your target into a lava surface)
Bloodletting (increased damage doesn't matter for leach)

I am not 100% sure about the Destroy Summon damage.

Thanks! Im playing through with a low int caster and I am going to try many of them.
