Add map exception for items that only work in PVP

[Roku]

Hey guys,

as you know, some items only work in PVP environments (e.g. Siege Suit, ID 15047). When these items have a MaxHP bonus, your HP will drop once you enter a PVP map, because the bonus is suddenly applied. You have to heal up to be at 100% again.

I have a few custom items that only work in PVP, but I would like them to also work on one specific map (let us just call it specific_map). This specific_map is the pre-woe castle map, so I want the items to work there, giving players the chance to heal up to 100% through an NPC and then enter WoE castles with 100%.

The item restrictions are declared in item_noequip.txt, with the restriction being "1 - All normal maps", so it works only on PVP maps.  Does anyone know if there is a simple way (using db files) to make the items work on my specific_map, without disabling any features a normal map would have (e.g., no pvp, flywings allowed)?

I want the items to work on specific_map, but I don't want PVP enabled or (for example) flywings disabled on that map :/. Hope you can help me!
