Name the caster and target type parameters of the 0xA3 sender, checked against live captures
Ghidra v1799 · 2663303
bParam2 fills byte [6], just before the GUID at [7], and bParam3 fills byte [0xb], just before the GUID at [0xc]. In nine captures from a running game, Thunder Storm hits read type 0 and uid 1 for the player at [6] and [7], with monster uids at [0xc]. Not changed because the tool treats it as chosen: nStatId fills [4], which read 2 in those captures, the skill's level. The plate's aura stat update looks off for the same reason.
