Further Explanation of Training

From Nizheroes

• Being trained gives a +5 bonus to that skill (or skill group, being traind in a skill group gives training benefit to all skills in the group).
• Skill Focus adds a +5 bonus to a skill or skill group (instead of +3). A character must be trained in a skill to aquire focus in it.
• In addition to this bonus, characters add their level to all skill modifiers.
• Therefore, a character's modifier in a skill is equal to (level + ability modifier + 5 if trained + 5 if focused).
• Thief levels count as 2 higher for determining skill bonus, however the Thief is trained in 10 + int skills, not 12.
• Gaining a permanent int modifier increase grants additional trained skills as normal.
• Any skill listed as 'trained only' can only be used if a character has training in the skill.
