Do runes stack with damage on weapons

I have a question. Let’s say I have 1-20 lightning damage on my weapon, if I insert a rune for 1-50 lightning damage, will they stack? And if I insert two runes for lightning damage 1-50, will they stack?

Yeah it stacks. Unless you have an unstackable effect. Like having a weapon with immune to freeze and then adding a rune or jewel for immune to freeze won’t do anything extra. It’s pretty obvious what will stack (things without numbers won’t stack).

I wouldn’t use runes for that purpose. There are way better uses for runes. You can use a Gem instead. (Topases give lightning-damage.)

Or even a jewel, if you have one. But I would save those for crafting. (Jewel are much rarer than Gems.)

That said, on the other hand, the runes, which give elemental damage to weapons are pretty common. (But they’re also commonly use for runewords…)

Haha now that’s an entirely different issue. But I agree. Unless it’s early game. And people often use Ist runes for the MF. I tend to socket PGs (or less) for damage early on, especially poison for the merc before I have an insight.

Laughs by putting an ist into helmet because P- stone gives just a little bit less mf

Haha well a lot of people are playing SP where these things are worthless eventually.
