One of Tactics Maiden's central features is its skill point system.
Leveling up through combat experience yields 1 skill point for even levels and 2 skill points for odd levels.
These skill points can be used to boost either the unit's attributes (HP, Atk, Pow,...) or one ore more of its 4 class skills (in this example 'Charge', 'Shield Allies',...).
Each skill or attribute can be boosted up to 3 times which results in 4 stages:
Stage 0: no skill points invested
Stage +1: 1 skill points invested
Stage +2: 2 additional skill points invested
Stage +3: 3 additional skill points invested
In other words, 6 skill points are needed in total in order to max a particular skill or attribute. While stage 3 is usually the most rewarding one, the player is often better off with splitting skill points among several skills and attributes instead of maximizing just 1 or 2. This is especially true during early levels where fewer skill points are available.
It is also noteworthy that skill points can be reset and redistributed whenever a unit is out of combat.
Especially on harder difficulties, players might find themselves tweaking their units via skill points (and items) quite frequently.
Let's have a look at the 'Knight' class to see how this works in practice:
Should I invest more skill points in HP or defense values to make the unit more durable?
Or maybe some skill points in MP to avoid running out of 'mana'?
Increase Atk to do more damage?
Increase Pow to further strengthen 'Shield Allies' and better protect your other units?
Invest skill points in 'Cleave' for devastating damage against leather wearing armor units?
Increase Retaliation damage for a 'counter attack strategy'?
Or maybe in Mov to make the unit move faster?
Of course there is no 'right' answer to theses questions.
Everything depends on the player's preferences, play style, the kind of challenge lying ahead, as well as other available units.
