Players can learn a late skill right away by spending points in the wrong place

A skill tree only guides the player if its gates hold. Common mistakes let people skip the early part, or count the very skill they want towards its own requirement. Here is one clear check that says yes or why not.

Why this works

When a skill is greyed out, the player's first question is why. A fixed order of reasons gives one clear answer at a time, so they can fix the first problem, see the next, and never wonder whether the game is broken.

When not to use it

Skip tiers and gates when you want a free, open choice of skills, or the tree is tiny. Locks then only hide options; let the player take anything and use cost alone to keep things balanced.
