So I've not played but seen wanderbots videos on the game in steam. But a way to get both for one is this.
Make the summoner class with staff and dagger mastery. The summoner gets four specific skills that I recommend. Skill one summon drone: The drone is a permanent summon till death, so it takes up a slot to re-summon. Drones are a arial summon that follows you and is a ranged attacker. The drone attacks the closest enemy. And has a limited range and fire rate.
Next is the angel. The angel like the drone is a permanent summon till death and will take up a spell slot as well. The angel does the same thing as the drone but at a fraction of the attack speed. And in exchange for that loss in fire rate give it produces a spearical AOE that heals at the same rate that it attack but for one hp. And like the drone attacks the closest enemy. With that summoners can have both if they want.
The next spells I'm suggesting are support spells for the summons. Temporary range increase which gives summons the ability to attack further and have a bigger heal area for the angel. And the other is temporary attack speed increase which give summons faster fire rate to attack and heal respectfully. And those are the base of each. Plus whatever ya make to compliment this.
