【FGO】 Melusine and Castoria/Koyanskaya/Oberon 1-1-3 System Triple Demo

Today's 90+ Hunting Quest node is a great test case for Melusine on 1-1-3 nodes. Here's a bunch of plugsuit-less, any MC examples.
Note that if your Melusine is NP1, you may fall short on damage, so consider CE and MC choices to help with that.
With Castoria+Koyanskaya, Melusine's Skill 3 only needs to be level 5~6. But it's the version with the lowest damage. Here it works out because Koyanskaya's Anti-Humanity slayer buff applies to skeletons.
Melusine's Skill 1 does not need to be level 10, but if it isn't, you'll need compensate for it by either unlocking her Append 2, using a 60% CE, or using an MC with 10% charge.
