If think there is one minor oversight in tactician mode: with the extra enemies I'm constantly overlevelled, and I don't go out of my way to kill everything/get the best xp quest rewards.
At one point in Cyseal the party was level 9 fighting 6-7 enemies, wasn't very challenging.
If you are having problems in tactician mode, get an extra mage with 1 point in all magic skills.
The spells that can make any fight easy:
- bitter cold: costs 2(!) ap, has a great base chance to work(120-130% at lvl3) and almost nothing has immunity to it. Just take the most dangerous enemy out of the fight while you deal with the rest.
- slow current, malediction: the next best things for 2/3 ap, if they land they'll make the enemy do close to no damage.
- midnight oil, boulder bash: 3 ap midnight oil is op, just get a fire wand and you can light it up for another 3. It blocks los, then you can start dropping boulders on them: don't need vision for that and adds some extra burning surface. If you are feeling cheeky you can try and find an angle to teleport one particulary annoying baddie on your side of the smoke at the start.
