Neith, Musashi, or Ranvir?

If you have Miki or Tarlak or Wu Kong levelled, I would advocate for either Neith or Musashi.

Logic of not levelling Ranvir if you have Wu Kong

Math comparison of the Ranvir vs. Wu Kong, looking ONLY at tile power. Doesn’t linearly translate to damage dealt because the math isn’t linear.
Thread here for damage calculation: Damage Calculation

Math will look at 3x tiles hitting an enemy and NOT doing crit.

Wu Kong
+185% damage. Thus 3 tiles becomes 8.55 tiles equivalent power. Then with a 32% miss chance this then becomes 5.814 tiles power

Ranvir
+195% damage. Thus 3 tiles becomes 8.85 tiles equivalent power. Then with a 35% miss chance this becomes 5.725 tiles (LESS than Wu Kongs).

On top of not charging tiles more than Wu Kong, Ranvir costs more to max out in terms of food, feeders, time, emblems (+emblem food & iron costs) and ascension materials.

If you have another Blinder levelled already (e.g Justice, Drake Fong or Joon) I would vote for Musashi or Ranvir.

Based on your answer above, I would say to level Musashi as he will give you some DoA + Sniping ability. Neith would be the next recommendation followed by Ranvir last.
