(This is a ramble/brainstorm specifically pertaining to Evolving-ARPG group mechanics. If you are not interested in that sort of niche thing, I suggest you slowly walk away now. Any sudden moves may be misinterpreted as interest in the subject.) Of all the subclasses of upgrades, I feel horns are the hardest to do in a satisfactory way that balances creativity and realistic boundaries of potential group legality. Most start off easily enough: small horn nubs of some kind. “Growing” them out tends to get more muddled. Evo-ARPGs tend to focus on a single artwork card (or a multiple-image gif) to help visually show members what an upgrade is allowed to look like. Some of these examples have unique traits (ridges, velvet, multiple prongs, scaling texture, etc) that are locked to one horn shape, while everything else is a smooth typical horn. This is a good system for groups that want to limit horn versatility or keep a species more recognizable from others at a glance, but for other
