If i could call it i would call it "divine" rank(color of rank would be black) and i suggest it costing 499.99 usd on the store(aka 425 dollars usd with the 15% off covid sale) or as for benefits of the rank, if say it should be these:
ability to acesss the "divine" cape at ::dzone off a new rack(gives the same bonuses as a f cape/donator cape, but it has +1 defence bonus more then infernal cape across the board and has +1 more prayer bonus then the fire/donator cape.
teleport for free to the same location as the revenant cave teleport(maybe call it ::revenant) but can only use 2 times a day
All new item called "Pod Increaser"(able to buy it off of the new NPC standing next to the divine cape rack)(Costs 4000 pkpt, is untradable)(lost on death, but not the Royal Seed Pod, only the attachment is lost) with a all new set effect: If you combine this with your royal seed pod, you will now be able to make a new item called the "Grand Seed Pod" and the effect will be you will be able to teleport at 31 wilderness instead of the usual 30.
if it were up to me i think the new NPC where you buy the Pod Increaser should be the NPC from OSRS named "Ajjat" but instead of him wearing an attack cape he would be wearing the new divine cape.
extra mage arena cape charges: 13 (3 more then legendary)
npc drop rate: 37 percent (2 percent more then legendary)
extra PVP key drop rates: 55 percent (5 percent more then legendary)
extra PKP per kill: +40 (10 pkpt more then legendary)
extra blacklist spots: +7 (2 more then legendary)
extra bank slots: +592 (80 more then legendary)
special attack restore: every 25 seconds (5 seconds quicker then legendary)
extra custom kits: +25 kits (5 more then legendary)
extra skin colors: +14 skins (1 more then legendary) (all new skin color for only divine ranks)
extra trading post slots: +20 slots(4 more then legendary)
Free donator Points upon purchase: +1750(950 more then legendary)(i think this is fair as long as the divine rank would cost 499.99 usd)
I would love for some feedback on this idea!
