The instructor and master wands hit tougher when attacking bigger monsters (dragons, giants and orks, oh my!) *. The master wand, naturally, will get a better bonus over the instructor wand. This does not use the special bar. Apart from that, the
RS gold instructor wand can hit twice per throw (such as the DDS) for 33.3% of the exceptional bar and the instructor wand could do the same for 25% of the bar.
The obsidian staff (Toktz-mej-tal) strikes 30% more difficult when from the
cheap OSRS gold Karamja Volcano*. Mystic battle staffs cast three spells at a time when using the particular attack. This only applies when auto-casting contemporary magic charms. (Takes up 50 percent of the bar.)
