>>53166966CDR lots of CDR something like Energy AMP that works really well with Clefable's Unite and EXP Share to season the food scraps your partner will be forced to eat but it'll be nutritious for them because of your EXP Share seasoning, the last item is optional to your preference.
>Buddy BarrierFor more health and shields with how low the CD on Clefable's Unite, you'll be using it a lot especially with CDR also it works synergically with Energy AMP because Clefable's Unite is a hybrid of Healing and Damaging.
>Focus BandGives a little resistance and the healing scales with health which also scales with EXP Share and Buddy Barrier, it works well working along with Clefable's healing to help survive a lot of things in a pinch.
>Score ItemsSpecs for bigger heals which makes Magic Guard give bigger shields which makes Gravity's Butt Slams stronger which makes Unite damage bigger..It just scales everything on Clefable.
Cookie makes you a health tank especially combined with EXP Share and Buddy Barrier which it's shield gets stronger because it scales with health, so you can kinda sub-tank with the main tank like Brigitte with Reinhardt in OW or Taric with any toplane Tank in LoL.
>Emblems6 Greens/7 Blacks, if you want to stack CDR with Energy AMP.
6 Greens/6 Whites, if you want to stack Health with Buddy Barrier.
Both works with Specs, if you prefer that instead.
TL;DR: the common Clefable build is AMP/EXP/BB with 6 Greens/7 Blacks.
