>>36427882>As for not relying too much on RNG to determine rarity, how about certain pokemon can only be found by looking in certain places or doing certain things?Hidden Grottos were pretty much just what you'd ask for, a reward for exploring in finding a Pokemon with a hidden ability (which normally was in that dumb DW webgame)
Putting something out there for the player to possibly even miss if they aren't really looking or paying attention, makes the adventure feel more real when you spot something like a hidden nesting spot in the trees of a forest instead of pacing back and forth on dicerolls.
