Go to collections, armor, leveling and choose the "Dreamer" class item. For me it was a cloak since I main a hunter. The power level in this class item is 21, so it drops your level significantly. Check your vault 1st and see if you have any 750 or lower armor/weapons. If not, then go to any planet vendor and buy their gear. It's all 750. You need to be below 750 to not engage with another guardian who's trying to do a forge legitimately. Hope this helps
