So, Marbit, could you perhaps include some ways for non-casters to potentially capture an enemy unit?
At the very least, a net item of some sort. Like so:
Small Net (Lesser Accessory)
A Small Net may be used as an action; this consumes the Small Net.
Target an adjacent, non-heavy, single-tile unit. User must roll 2d6 greater than (enemy's combat + enemy's hits + 3 if dodging) - user's combat. (Automatically succeeds against Stunned, Calmed, Incapacitated, and Immobilized targets.)
If successful, the target becomes Netted.
New Status Effect: Netted
Netted units are considered Incapacitated as long as they remain netted. A unit may be un-Netted if another unit spends an entire round adjacent without doing anything else or being attacked. Multiple units may attempt to free a unit simultainiously.
A Netted unit is also freed when an adjacent unit Strikes it or it is hit by any sort of fire (as in combustion) attack. However, the unit still takes damage from this attack at defence 0.
So, there's your most basic version of a net. More advanced versions (requiring higher level crafting spells) might provide a bonus on the capture roll, be usible on heavy and/or multi-tile units, be reuseable or even useable at range.
