-standard wealth and items(one magic item of level +1, one of your level, one of your level -1, and wealth equal to the price of a level -1 item)
-PHb, FGRG, Dragon for races and classes, no races from the MM, no playtest or preview material.
-All books available for material.
-Some options may be disallowed.
-Competitors are coupled randomly.
-There will be two different arenas; you won't know in advance where you'll fight; there might be traps, obstacles or monsters; the arena for the final will be chosen randomly between these two.You won't be able to escape the arena so that is not an option.
-You will have an extended rest after each fight; you can choose not to take an extended rest and keep benefits deriving from the fight that you haven't used(pact boons, temporary hps, action points, whatever)
-You win if your opponent:
* falls unconscious on his turn due to reaching 0 hp and you can attack him on your subsequent turn
* falls unconscious during your turn due to reaching 0 hp and fails a death saving throw on his subsequent turn
-The fight continues if:
*An unconscious competitor manages to recover from the uncoscious condition
*An uncoscious competitor fails to recover, but the opponent is unable to attack him (example: he is immobilized and only has melee attacks)
-You can have one item or weapon ready at the start of the battle. Well, except for shields, that'd be unfair. So yeah, for example you can have a sword and a shield ready without needing an action, but you'd have to spend one to take a potion out.
