It is not that difficult really, tough adding augmentation would be difficult as it requires you more resources. You will have to take some in debit and stick to cheap augmentations (I went with bone density augmentation).
Here is an example with sum 2 10.
In a gist you have focused concentration 1 for elemental aura spell to augment unarmed damage. (and a cool factor - electricity/fire/radiation(?!) strikes). I did not give you ranged weapon skill because you can use spells.
Unarmed:
5 agility + 6 skill + 2 spec + 2 mentor = 15 dice in your favorite method.
Damage:
8 strength + killing hands 1 + critical strike 1 + bone density augmentation 2 = 12 (13 if you take striking callus - my chummer did not include that.)
Need more unarmed damage? cast elemental aura at force 1 with reagents to set the limit ( you can sustain it with focused concentration) - on average you get 4 hits so your unarmed attacks just got into the domain of 16 (or 17) with an elemental effect. - You are comparable to the cyber troll with the axe.
For range combat you have 6 magic + 6 skill + 2 spec + 2 mentor = 16 dice at range so you are also dangerous at a long range.
so you should be really good for fighting, you have 14 dice to dodge bullets and 5 body/willpower + 3 armor from bio augmentations - so you are quite durable. If you need more than that you have improve intuition but then you'll take -2 sustaining penalty. (or have a spirit cast it on you).
Your initiative is always very good with improve reflexes 3.
The rest of the spells are utility to make up for low skills - such as levitate invisibility, heal, illusions - they are not meant for combat but to give you interesting things to do outside combat and round out your playing experience.
