Nightingale ATK debuff is around 30%.

Tested it with Chimera in Beelzebub Tundra; their 'breath' damage to Merlin fall from 3k (about 3.2k) to 2k (about 1.8k) while Lancelot damage to Suzuka fall from 3k to 1k combined with Suzuka attack debuff; potent enough that her heal effectiveness increased.

Now if only Nightingale can spam her NP (LOL).
