The base combats are similar so we will cover them in one section. You will always be faced with gate guarding units. These will fall relatively easily and you will be taken into the boss battles. The easiest way to defeat these gateway units is to take out the enemies tactical leader. Focus your attacks here, and things will go quickly. Now, onto the bosses.
Base 1: Snievan
Take away the weaker units as quickly as you can, and be wary of his floppy eared friends. They carry some strong magical attacks. Snievan can take out whole units in 1 turn, so be wary, and ready to heal often.
Base 2: Zuido
Zuido’s fight will be near identical to Snievan, use the same tactics.
Base 3: Ludope
Get David to lead a unit, and try to get Gae Bolg used quickly. This will leave you with no one but Ludope to kill. Ludope likes to throw out curses, and has devastating attacks that can kill multiple units. It’s simply a matter of wearing him down.
Base 4: Hannah and Hinnah
These girls are fast, and will often get multiple attacks on your units per turn. The best option is to focus n killing 1 twin, then the other. The second kill will be much quicker.
Base 5: Young
You should go far as many simultaneous attacks as possible, even if it means breaking deadlocks. This will be a long fight so settle in and play for the long term.
Base 6: Milton and Cyclops
At base six you will end up with back to back boss battles.
He is pretty easy, just watch out for his “Iron will” ability. This allows him multiple attacks in a row. Once you are done with him you will go right into Cyclops. Cyclops has heavy damage attacks like Gae Bolg which will be used ever 3 turns. Your best bet is to stay on the defensive and use combination/special attacks when possible.
After each base you should be visiting the Duke of Ghor for goodies and possible side quest.
