Read as many runes as possible (Regeneration will not increase as a player may think because of buff penalty) with most enemies dying after one to two hits. (Especially useful when combined with Pelting Strikes).
If the player wants to do Fire damage instead of Ice, they can equip the BFG and cast Archangel's Wrath (requires revered lore & focus for maximum effectiveness).
Gloves with elemental modifiers (can be dropped or bought) like conversion Physical to Fire/Magic/Poison can be used to change some of the damage of the BFG to one of these elements (ice is not needed since BFG is ice)
As the weapon will spawn when this Combat Art is cast, there is no need to find other weapons with higher damage at higher levels.
Very effective vs monsters with low ice resistance (ex: dragons)
If Buff level is high enough, it is possible for the BeeEffGee weapon level to far exceed the maximum level weapon equipable for a given character level. For example, the maximum normal weapon level that can be equipped by a level 100 character is level 127, whereas there is no limit to the level BFG weapon that can be equipped.
