Flash Rune

The flash rune is a rather weak rune that is used on only weak weapons in Starhunters.

In-Game Description
"A rather weak rune for beginning runers. It slightly boosts firing speed."

Tactics
Since the Player can have up to 3 White-tier runes on one weapon, it is advised that they apply also the thorn rune and the feather rune on their first weapon (which should be the.14 iron ryfle if on Easy) - as long as it is a White-tier weapon. It is not advised to apply White-tier runes on any tier above White itself.

Applying the flash rune to any weapon will grant access to the ember rune, spark rune, snow rune, and toxic rune, so it is advised to apply it to any starting weapon as of rune access use.

Applying 9 out of 11 White-tier runes to weapons, including the flash rune, will unlock the burst rune for use.

Location
The flash rune can be applied by virtually every NPC on any weapon with said requirements, and all NPCs that know it will always be willing to teach it (unless the Player has significant infamy against that NPC race).
