Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Criticize my 3 Mage/1 Hybrid Party

I recomended Summoning+single element,because it is better at covering Immunities than investing in a second magic school. If as a single element+summoner mage you get a +1 Necro ring than you qualify for Blood infusion. After you get Blood Infusion with the necro,all you have to do is switch between the native elemental infusion and blood infusion.

If you want more infusions,you can go find gear with +1 in the desired area. The game plan is that you get escapist on all 4 mages,proc the encounter,run only to come back with properly attuned Champion Incarnates.

Also there is one way you can make a high str warrior work in a party of mages - poly+geo,buff that Medusa Head to high heaven.

Edit:I will also asume you don't like the 4 summoner route so I will leave here this alternate party setting.

Red Prince:Pyro+two handed str to qualify for plate armor,int for damage and gear that boosts aero and warfare to 2 for teleportation spells and whirlwind (best aoe damage spell for melee mages,scales with staff damage). +Pyro gear over +two haded gear,because your starting pyro will be ghimped by 1. You start your character with Bull Rush (best mobility spell for melee mages at character creation) and Chameleon Cloak

Beast:Poly+Geo,he will start off as a Poly and you will have to use the mirror to get rid off his +2 fin and move it to intelect. If you find the recepe for Earth damage Runes,then your priority will be to have them crafted for the Beasts weapons. The best part about Poly is that all skills can be cast with double wands, but I would recomend 2 str weapons with earth damage (runes) to kill mages and rangers faster.

Loshe:Geo+Hydro,start off as Cleric,then build up geo for armor restore, with her as the healer,she will strugle trying to beat the party when her demon goes crazy. Don't give her too many attack spells.

Sebile:Summoner+Warfare. Her totems and incarnates will take care of dealing magic damage,let Sebile auto attack with a bow to her heart's content. The only warfare skill you will ever need is Rage for her bow,totems and incarnates to crit. +Necro gear for more utility skills will be a boon. You could sacrifice a point from warfare to get poly for bull rush (which I think can still be cast with a bow equiped,for mobility) and chameleon cloak.
