Question about Ensign's Tomb High-Damage Swordsman build

i have a noob question about the attributes, for swordsman ship and strength is it the base 12 and 8? or is it 12 and 8 by adding the items? also is it suitable for PvE?

Swordsmanship 12, +3 Rune, +1 Hat
Strength 8, +1 Rune
Smiting 10
Healing 2

That means that you take it up to 12 yourself, so in essence, its swordsmanship 16.

does that make sense?

And yeah, as long as you have a good healer along, you'll tear up the mobs in PvE too.

ok thx jeshter that cleared a lot of things for me
