modify a pre existing particlle attack ie wyvern attack

hi everyone just wondering if someone can point me in the right direction or a tutorial etc that would help in learning how to modify a pre existing particle attack for example the flame attack on a wyvern and changing it to a different particle and the effects of the damage Ie not burning ?

I have created the particle so I am ok with that side of it but just replacing it is where I am stuck

The particle system is set in the notify of the Wyvern’s Ground Attack.

thanks mate I quite literally found this out today and got it to change! appreciate you commenting as without someone elses help I was still stuck cheers!
