While inspired by a clarifying question I had, I don't hate the idea. Especially the idea of only a certain amount being obtainable by anyone, but the full amount being obtained by showing support and donating to the server. I could also see it benefiting newer players by giving them a chance to survive in Ultimate and simultaneously weakening the emphasis outsiders put on Ultima's stigma of being pay to win.
Elaborating on what @Malcoren suggested, I think adding in a system/quest to add hit percentage to any weapon à la Claire's Deal 5 could be a reasonable form of access to this concept. It could also incentivize people to build on any weapons they find with 2 good attributes but a lacking hit percentage instead of just trashing them or selling them immediately. Additionally, acquiring the DTs for 50% hit instead of 80% may have the result of seeming less daunting and encouraging players to start seeing DTs more as a commonality than an expensive rarity.
