There are several ways to guarantee that a player
will eventually get random stuns in a fight, however there's no way to guarantee that every hit will be a stun. Of course there are ways to work around it, use items, effects etc. to practically stun someone every few hits.
Using Items to Increase the Stun Chance
-Using Items with stun chances, for example Gorbakh's Mace or Replicas of Gorbakh's mace.
-Using the Unique Silvery Bezel (for example Unique Silvery Flames Bezel for BC weapon) on weapons to increase the stun chance.
-Using amulets and rings that give stun chance (Like Balthazar's Stun Ring or The level 15 stun ring via the quest from the Gnome Spirit).
-Using the
Witch's Hat which is an event reward from October Seasonal Event.
Using Effects to Increase the Stun Chance
-Using the Rock Skin Elixir.
-Using the Might Charm.
-Using the Battle Skill Elixir.
Other ways:
-Using level 4 and level 6 combinations (Thirst for Blood and Greater Thirst for Blood).
-Using level 9 combination (Bear Super-Blow).
-Using Power Elixir or Extract of Power at the combo ending hit (applies for the two combinations listed above). It's not proven, however the super blows seem to stun more when these elixirs are used.
These are the ways one can try and use to stun monsters or other players.
Ways to protect oneself from stuns are:
-Using Elixir of Internal Stability. Greatly reduces one's chances of being stunned.
-Using the Fetters of Weakening arrow on an enemy to force them to re-start their combination (this works in cases of the enemy using physical hits or glaze). Making sure that one will not be hit by a Bear Super-Blow, Thirst For Blood or Greater Thirst For Blood and therefore is not in danger of being stunned via these super blows. It, of course, does not nullify the effects of the might charm, rock skin elixir, battle skill elixir or any other stunning effect from items or elixirs/effects
-Last, but not least, various symbols. Tubar-Dan Symbol of Inexorability (only received on Chainmail or Helmet) reduces the chances of one being stunned slightly.
