[Dragar]

Rather than a flaming arrows version I'd be inclined for the spell to just make them AP. That way it wouldn't be as strong and wouldn't require the Fire caster that is hard for Man to get hold of.

An Ench 4 with E2 requirement sounds about right to me, not too easy to get but not too hard either.

In terms of the Tarts I think the combination of changes will just strengthen the strategy. If GoR is going down for other reasons I feel Tart cost should rise further - I don't see how Chalice/GoH holders are not better off compared to everyone else by this. They are the only ones who can really make the strategy powerful, and it just got sweeter.

In order to separate the use of GoR for other purposes, would it be feasible to have all Tarts start as commanders, but up the death cost dramatically? That should stop mass production - massing gems of one type in very large numbers is harder than moderate numbers of two, excepting gem types that can be produced by items.
