Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Help build Tactician Mode!

If you already know which spells are good, simply pick them early in your new game.

Tactician is relatively more difficult in the beginning than in the end, likewise normal mode, but the learning curve is ok if you already completed the game in normal.
In general, fights are made easy by having initiative (a few leadership points and speed?) and controlling ennemies asap (mage spells, man-at-arms knockdowns and marksman special arrows).

You might want to pick different companions so you discover their stories (what did you do the first time?).

The very first fight can be difficult if you don't select proper skills. The spider summon, the heal, the frozen cc, ricochet and knockdowns are very good to take at creation for that fight. Scoundrel invisibility is handy to ransom the city right after.

It might be helpful if you gave your current thoughts on what you'd like to build and why, as it would be easier to simply react to it rather than write a full guide.
