Editing This Is Not A Test/Tactics (section)

==Level-up Strategies==
Stat increases have a theoretical maximum, but are also capped by the model's Level. Once a model maxes out all of the stats for its level, it can either choose to automatically gain a Skill/Upgrade/Mutation, or to force a Promotion if one's available. That said, this requires at least six advances, so you've probably already rejected a Promotion at least once. 

Leaders typically have either a unique skill, one barred skill tree, and a beefy initial stat upgrade, or access to all skill trees and more open skill slots. Elites start with Ranged and/or Melee increased by a few points and a unique skill, plus their choice of more skills. In either case you can't Promote them.. but rolling "Promotion" on the level-up chart lets you choose any other result on the list. Remember that Income and buying wargear happen ''after'' you spend EXP. If you've been saving up for better armor on an eligible model, it may be in your interest to wait a game to roll any potential Elite/LDR advances in case you get a surprise Wounds bonus. 

Specialists have one or two unique skills and (usually) a small stat bonus.
