What are the most efficient glyphs for the duels against the Brothers?

I have the impression that Ritual can be very damaging, but it's hard to use as you need to triangulate accurately against live target. Hawk is a sure bet, as it does have "autoaim". The circle protection can be useful, but you can't use glyphs meanwhile. Hast is pretty situational, of course, but against some enemies it gives you the boost needed to evade their attacks. I still have to try more glyphs, like Repulse or Histeric or Wasp.

BTW, simple use of throwing colors damage the Brothers, unlinke some people believes, but the damage factor is verly low. I only could lower the HP of a Brother to half using all my color in that manner. The trick is only using the color as the color wheel of the Brother turns and signals a specific color, that is the color you have to use.

It really depends on the brother.

For some you need magnet, others repulse, hawk in some, owl and mines in others, etc.

Then the game should give you some hints, "try & test" is a pretty boring method.

Most of it is logical. The auto aim golem is slow, so it won't work against a fast moving brother, Tyrant for example.

I just beat my first Brother! It was the "bird jail" one. But they don't give me a bit of extra color after the fight, like when you kill a Pangolin. Mff.
