Armor curve

Vanilla's armor formula (HitData.DamageTypes.ApplyArmor) is tuned around "normal" armor — roughly the amount any character is expected to be wearing for their progress, regardless of build. It has no defensive talents to account for, so it already hands out solid reduction at that normal level. If TalentTree left it untouched and just added armor-boosting talents on top (Iron Skin, Ironclad, Bulwark's Edge, Warden, etc.), a Bulwark wouldn't feel meaningfully different from anyone else in the same armor — and a fully invested one would trend toward near-total damage immunity.

So the replacement curve doesn't just cap extreme stacking — it nerfs armor right around the "normal armor" point itself (the curve's balance point, ratio 0.75: armor worth 75% of an incoming hit). At that exact point, vanilla gives 67% reduction; TalentTree only gives 50%. That gap is the point: anyone wearing the armor vanilla expects, without investing in defensive talents, is tankier in vanilla than they are here. To get back to (and past) vanilla-level tankiness, you need to climb further up the curve than "normal armor" would put you — which is what Bulwark's armor talents are for. A hard cap of 80% on top of that ensures even a maximally-invested tank still takes at least a fifth of every hit, so "fully committed to defense" stays strong without becoming literal immunity.

Example for a flat 100-damage hit (reduction shown, not remaining damage):

The ratio is what matters, not the absolute numbers — the same curve applies whether you're tanking a Greydwarf or a boss. The takeaway: TalentTree's curve sits below vanilla's at every armor value, including the "normal" amount you'd wear without any defensive investment — that's the actual nerf. Bulwark's talents are what let you climb back up (and the cap is just there so even that climb has a ceiling).

Skill damage: halved, and made constant

Vanilla rolls your weapon-skill damage factor randomly each hit, centered around 0.4 + 0.6 × skill factor — at 100 skill that's already most of the way to double your base damage, before any talent gets involved. Two changes here:

• The skill contribution is halved to 0.4 + 0.3 × skill factor, so raw skill grinding is a smaller slice of your total damage and talents/gear matter comparatively more.
• The factor is also made constant instead of randomly rolled per hit. This is mainly so the numbers are legible: with vanilla's random roll, your damage already jitters hit-to-hit, which makes it hard to tell how much of a damage increase actually came from a new talent versus just a lucky roll. With a fixed factor, the damage delta you see after unlocking a talent is the talent's contribution.

Bow draw speed scales less with Bow skill

Vanilla speeds up your bow's time-to-full-draw as Bow skill rises: the required draw duration is Lerp(drawDurationMin, drawDurationMin × 0.2, skillFactor) — at 100 Bow skill you reach a fully-charged (max-damage) shot in just 20% of the base draw time, i.e. five times faster than at skill 0. TalentTree raises that high-skill floor from ×0.2 to ×0.3: a maxed archer now reaches full draw in 30% of the base time instead of 20%. Nothing changes at low skill (both start at the full drawDurationMin) — only the top end is pulled back. Bow skill still meaningfully speeds up your draw, just not to the near-instant full-power shots vanilla allowed. This is the ranged counterpart to halving the skill-damage contribution: it keeps pure skill-grinding from letting a high-level archer fire max-charge shots almost as fast as uncharged ones.

Stagger multiplier scales with Blocking

Vanilla always doubles stagger damage on a block (2×), regardless of skill. Here it scales from 1.5× at 0 Blocking skill up to 2.0× (full vanilla) at 100 Blocking skill — investing in Blocking skill has a tangible, visible payoff for shield/stagger play instead of being a flat bonus everyone gets for free.

Weapon blocks don't benefit from Blocking skill

In vanilla, Blocking skill also strengthens parries/blocks done with a plain weapon (no shield equipped). That's removed — only shields benefit from Blocking skill scaling and the timed-block bonus. Weapon blocks use their base block power only, which keeps Bulwark's and Warrior's shield/parry identities meaningful instead of letting any weapon match a shield's blocking power.

Parrying costs stamina again

In current Valheim a successful timed block (parry) drains almost no stamina — perfect blocks are effectively free, so there's little cost to parry-spamming. TalentTree restores a real stamina cost to parrying: a timed/perfect block now pays the normal, absorption-scaled block-stamina drain instead of the near-zero perfect-block value. Parrying is still very strong — you negate the damage, stagger the attacker, and build adrenaline — but it's no longer stamina-free, so mistimed or spammed parries drain you and stamina management stays relevant in drawn-out fights.

Creature armor by biome

Most vanilla Valheim creatures have no armor stat at all — incoming damage to them isn't mitigated the way player damage is. Since the armor curve above changes how armor behaves for everyone, TalentTree also gives creatures a small, biome- and threat-tier-scaled armor value, so the new curve interacts consistently with the whole game, not just with players. Tiers are Light / Medium / Heavy / Boss; Meadows creatures are unarmored at every tier.

A few familiar anchors: Troll (Black Forest, Heavy → 6) and The Elder (Boss → 8); Abomination (Swamp, Heavy → 24) and Bonemass (Boss → 30); Stone Golem (Mountain, Heavy → 35) and Moder (Boss → 45); Lox (Plains, Heavy → 46) and Yagluth (Boss → 58); a Seeker Soldier (Mistlands, Heavy → 52) and The Queen (Boss → 65); Morgen (AshLands, Heavy → 60) and Fader (Boss → 75).
