In fact, the best runewords in Diablo 2 Resurrected is one of the most overwhelming. Insight runeword is at its best when used on polearms or staves, but not many players use it that way. However, in order to benefit from its Meditation aura, equipping it to their mercenaries is an option for most players, as it greatly increases the player's own mana regeneration rate.

Polarms will be more popular than staves as the base for this runeword, but if you want an Insight stave, you can basically use the same recipe to craft it. RalTirTalSol is the runeword you need, it should be noted that you must add the runes in this order, otherwise you will not be able to get the item you want.

Any polearm type except the bardiche will do, as the bardiche will Buy Diablo 2 Resurrected Items only have three sockets at most, and the weapon must also be obtained from the aforementioned area.
