We all know how to burst (that i know of)

Fire can attack 4th and 5th round but other elements can't do it (idk if this works for wind 1 shield smash 2 unload wall 3 cord 4 strongest atk just in case i made a wind burst method)

Theory: All elements can attack

Before i start just want to say it is a THEORY i dint test it YET

water- I think if a waters freeze works then he is able to attack only on 4th round but if it doesn't he/she has the backup of sleep (just in case freeze doesn't work) and on 5th round Shrink

Earth- I think if a earths tera works(or tree bind depending on how u burst) he can attack only on 4th round

Wind - If cord spell works i think u may attack but only on 4th round

If you dont understand i will be happy to reply to u
Note: I didnt test this Yet just a theory
wind part i will try when my wind is able to start bursting
