How do you gain from 99.5 please? Uoguide says the following: "99.5 - 100 - Level 3 and 4 Treasure Maps (best to GGS each point)." Does that mean decoding? Done that with a dozen maps and no gain... Than there is the option to create wall maps, but you need a completed L5 map, which you can only decode with cartography skill at 100. So how can you GM that skill?
