Weapon Upgrades

[pepsiboy]

Is sacrificing health the only way to upgrade weapons? I see old guides suggesting could upgrade them at the forge. Has this since been reworked?

Right now yes. It is the only way. It been reworked with Medallions update. Since that update Astara (Forge) can refine medallions instead upgrading weapons at cost of gold.
You sacrifice 25% HP in the Blood Altar, and it can be lowered to 12.5% with Skill Tree perk (there is one that lower Blood Altar cost by 50%). Then the upgrades feel almost free at cost of around 30-40 max HP.

You can find at least one weapon in each biome that is at the same level as the biome. The game always invite you to change weapon.

-- level 1 -- Village, Mines, Huns Camp
-- level 2 -- Aqueduct, Academy
-- level 3 -- Tower, Temple (+ bosses after level 2)
-- level 4 -- Garden, District
-- level 5 -- Palace* (+bosses after level 4)

I bolded biomes that include Blood Altar -- the Altars always upgrade weapon to level of biome + 1, Then, for example in Village you will get level 2 weapon, in Tower you will get level 4 weapon (and it's the most worth upgrade)
*Palace and one more biome should be added with 1.0 according to roadmap

All weapons scale the same in DPS and it is around
75 -> 100 -> 125 -> 175 -> 250
As you can see, the scaling is almost linear, and it's always worth to use Blood Altar in Tower to get level 4 weapon that has more damage lift.

Currently, you can not use level 5 weapons in action, because you can only get them after level 4 bosses, and there is nothing after that, yet.
