Forge added.
Giga monsters now have chances to drop tier 1, 2 or 3 forging stones.
Which version of tier is based on monster Health (similar to how droprate on talent shards work).
Tier 1: base HP < 1000 → 70% drop
Tier 2: base HP 1000–2999 → 60% drop
Tier 3: base HP ≥ 3000 → 50% drop

Costs:
Tier 1: 2,500 gold/try, 10% each, guaranteed on attempt 11
Tier 2: 15,000 gold/try, 10% each, guaranteed on attempt 21
Tier 3: 35,000 gold/try, 10% each, guaranteed on attempt 31

Buffs by equipment slot and tier (T1 / T2 / T3):
Weapon: 10% chance on hit to deal +50 / +150 / +250 bonus damage (works for melee, bolts/arrows, wands — not spells/runes)
Armor: all resistance +1% / +3% / +5%
Legs: all skills (incl. magic level) +1 / +2 / +3
Boots: mana regen +2 / +3 / +5 per 2 seconds
Helmet: max health +2% / +4% / +6%

You can use any type of tier on any type of equipment.
If you forge your (for example) MPA with tier1, and then wish to change to tier2 or tier3, you buy "forge solvent" from npc Zara for 10k to remove the applied forge on said slot. Price to remove varies depending on applied forge level (5k/25k/60k).

IMPORTANT NOTE: if you use 10 tier 3 tokens and fail all, and decide to try tier 2 tokens instead, you will RESET your progress from tier 3 tokens and start from 1/21 (tier2).

Forge solvent is sold by Zara - npc between Edron depot and trainers.
