Skill Gain

Every swing, dig, and incantation rolls the same dice. This page documents the actual logic in Scripts/Misc/SkillCheck.cs — the file the server runs.

The basic flow

When you use a skill, the server makes a skill check against a difficulty window (minSkill–maxSkill, or a direct chance):

• Below minSkill: automatic failure, no gain possible (“too difficult”).
• At or above maxSkill: automatic success, no gain possible (“no challenge”).
• In between: success chance = (value − minSkill) / (maxSkill − minSkill), and a gain roll happens whether or not the attempt succeeds.

So the training sweet spot is work that is hard but possible — and once a task is trivial, it stops teaching you anything.

The gain chance (CheckSkill → GetGainChance)

For each qualifying use, the chance to gain 0.1 skill is computed as:

gc = ( (TotalCap − TotalSkills) / TotalCap        // room left under the 700.0 cap
     + (SkillCap − SkillBase) / SkillCap ) / 2    // room left in this skill
gc = ( gc + (1 − difficultyChance) × bonus ) / 2  // harder tasks gain more
gc × = GainFactor                                  // per-skill factor (1.0 for all skills here)
gc = max(gc, 0.01)                                 // never below 1%

where bonus is 0.5 on a successful attempt and 0.0 on a failure (post-AOS rules, which apply on this EJ shard). Controlled pets get a 100% bonus (doubled chance). The result is capped at 100%.

Practical consequences:

• Low skills gain fast, high skills gain slowly — both your total and the individual skill shrink gc as they fill up.
• Any skill below 10.0 gains on every use (skill.Base < 10.0 bypasses the roll), and each gain below 10.0 is a random 0.1–0.4 jump.
• The floor is 1% per qualifying use, even at 99.9 skill.

GGS — the Guaranteed Gain System

GGS is active on this shard (GGSActive = !Siege.SiegeShard, and this is not a Siege shard). Each skill tracks a NextGGSGain time; if you use a skill after that timer expires, you gain even if the random roll fails.

The timer length comes from GGSTable, indexed by the skill’s level (rows of 5.0 skill) and your total skill (columns: under 350.0 total / 350.0–699.9 / 700.0). Examples (in minutes):

Skill level	Total < 350	Total 350–699.9	Total 700
0–4.9	1	3	5
50–54.9	27	72	138
95–99.9	540	1440	2580
110–114.9	618	1662	3060

In short: keep using a stuck skill and the system eventually pays out — but at high skill the “eventually” stretches to days.

Skill cap behavior

• The individual cap is 100.0 and the total cap is 700.0 (Config/PlayerCaps.cfg; see the shard card).
• A skill only gains when its lock is set to up and it is below its cap.
• At (or near) the total cap, CheckReduceSkill lowers a skill you have set to down by the same amount you gain. No down-flagged skill, no gain. Set your skill arrows deliberately.
• Skill gain is disabled entirely in jail.

Gain amounts and accelerators

• A normal gain is 0.1 (modified by region SkillGain, normally ×1).
• Scroll of Alacrity on a skill: each gain becomes 0.2–0.5 while active.
• Mondain’s Legacy quest skill bonuses: gains ×2–4 while flagged.

Anti-macro: disabled

SkillCheck.cs contains the classic anti-macro system (max 3 gains per location/target per 5 minutes for flagged skills), but it only runs when PlayerCaps.EnableAntiMacro is true — and this shard has EnableAntiMacro=False (Config/PlayerCaps.cfg). You can train in one spot without the server pretending not to notice you.
