Those 3 already have the longest range of all the spells (I think it's foie>zonde>grants>barta). You can hit an enemy with foie from so far away the game won't even render the damage numbers. That's plenty enough distance. The range scales with the level of the technique so a level 10 tech won't go as far as a level 30. @Saber +7 If you want a ring model then do a custom model swap. Part of the reason for the costumes is to have variety not just in gear options but also in looks, so that not every single hunter is wearing a ring on their arm. @Noob Saibot The descriptions all do say stuff about the rings purpose, other than ylvis and bewbs costume which originally had different stats (ylvis had extra evp/less dfp and bewbs costume had extra fire resist. however, since the trap/search effects were actually unintended byproducts of the code and one of the original concepts for shields anyway, they were redone to include that). Frank the bunny costume 'terrifies your enemies' (increased debuff range), Catscratch 'incites allies into berserk rage' (buff range), Guardian Angel is self explanatory (I didn't write that one myself), Agent K costume is 'most effective at night' (increased edk), Minecraft costume 'don't let the darkness penetrate home defenesssSSS' (dark technique megid penetrates). As for the name of that one, 'Rainbow Ring' is the name of another server's ring (though it is a very different thing), and the texture's blocky pixelated look led to the Minecraft name being attached to it instead. There's no shame in using it over another ring just for looks. The costume effects are minor bonus extras which are not required, and halo souls are purposefully very easy to get so you can change if you want.
