Dodge stat?

[Dhex]

Slipstream is actually magic, you can't dodge magic but you can use spirits within to silence it.

You can dodge Slipstream, you can dodge Repulse as well - it's based on your Evasion stat. Evasion is hidden and as far as I have seen it can only be modified by using Featherfoot.

I've yet to see any information suggesting hidden modifiers in this game.

Parry Rate and Evasion are both "blind" stats that you'd have to test. Parry Rate is modified by DEX - this is stated by the tool tip and can be tested. Evasion is never mentioned outside of Featherfoot, is "blind", and thus is entirely impossible to accurately test.

What we do know is that it appears the order is: Evade(Dodge)>Block>Parry for which effect will activate.
