What if the Regent was an Ancient instead of a playable character???
His Majesty should be one of the Act 3 Ancients!!!
For the first relic, [[Sovereign Blade]] would be the same 2 cost Retain and 10 damage, it will be added to your Deck but cannot be upgraded. Metalworked would be an extra option at a Rest Site that you can use up to three times. You would be offered three choices:
to permanently reduce the cost of the blade from 2 to 1 (same as the Upgraded version)
Sovereign Blade now deals damage to ALL enemies (same as having a permanent [[Seeking Edge]])
Sovereign Blade now hits an additional time (same as having a permanent [[Sword Sage]])
You can add all the improvements by visiting a Rest Site 3 times. The Forge 5 at the start of each combat would increase the damage by 5 permanently.
The second relic would transform the Strikes and Defends into [[Minion Strike]] and [[Minion Sacrifice]]. They would be the same as now, so deal 6 damage draw 1 card and exhaust, and gain 7 block and exhaust. The idea would be to thin your deck every fight.
The last relic is what I imagine should happen if you collect both the [[Dingy Rug]] and [[The Merchant's Rug???]], with the extra regality of coming from the stars.
I don't think these are balanced at all, I just wanted to imagine the flavour of the Regent as an overpowered Ancient.
