Haven Magic Hero Build? (Campaign)

[Primaris]

I want to build a hero with a focus on Light Magic and some Air magic (Chain Lightning). What skills are a must have? I already have a build planned but I'm not sure how good it is.

Note: I actually have 1 extra skill point because of Heal Master.

i show my one Anton, but he is not like you my one is about taking absolute zero damage, and stun enemies by having light elementals, elite light girls, freze time, blindness to absolute stun enemies armies, i use "Staff of Sar-Aggreth" dynasty weapon on lvl 5 which buffs my spells efficency by 30%(makes stuns 1 turn longer for 5 turns of casting) and also makes my troops give +30% more damage to enemies, +MEDITATION i recommed this build also for duels, on that you will see alot of heroes like that which will stun you army to 5 units and keep healing over and over again, i go on TEARS way, is anyway a flying hero, teleporting alot, alot and alot along cities... will never make them fall also cause he can castle gate(upgraded portal skill) 2 times!!

HERE YOU GO;
