recently i have been flicking through the lizardmen codex and i wondered if this was possible slann of death focus of whatever gives you the extra pd plaque of the thing that gives you another spell to use 300pts can he fire off six spells a turn because he has four pd + pd in pool then he gets an extra dice for every spell
Well only 5 spells a turn but yes completely possible. Although getting 5 spells off a turn with four dice +1 for each spell will be highly dependent on which lore you take
The build you just described is actually generally considered the base for the Slann. One of those 'never leave home without it' types of builds. In most cases it's the only build people will use unless you plan on running your slann on his own without a unit.
