What about on our first turn we start out we are offered one item/spell. Each with a back story like a family heirloom, found object etc etc

None of them game breaking as these items are old and have lesser stats than the first tech items you can research since they are free at start and require no upkeep or cost unlike spells.

1.Breastplate

2.Helm

3.Boots

4.Cape

etc etc

For Those who want a mage right out of the door how about a starter spell like these ones. Could be from an ancient spell book with only one readable spell left in it. You cast during each combat and fade when combat ends but i think they would have to do about the same damage or same defence as your first tech items since you have to pump out mana each combat to call them forth.

1.Phantom Knife +Attack

2.Phantom Shield +Defence

3.Mage Missile Bow +Minor Ranged attack
