Ruukin,
You have basically three obtainable options that come with stats:
1.
Ulthork Hide Tunic (13AC, +3 WIS, -35 HP, +35 MP)
Auctions for ~75pp, so very cheap if you can find a seller. The -35 HP is a bummer. But it will look exactly like the Tizmak you saw.
2.
Cobalt Drake Tunic (14AC, +8 STA, +27 MP)
Auctions for ~1200pp, has a
bright blue tint, and not very useful stats.
3.
Arctic Wyvern Tunic (14AC, +10 STR, +8 DEX, +10 WIS)
Auctions for ~1000pp, has a
grey blue tint, but has actually useful stats.
So my recommendation for an exact fashion match is Ulthork, and for a good mix of fashion/stats go for Cobalt Drake.
