I believe the Stealth skill in this game gives your Rogue a passive chance to automatically hide in combat, which means the enemies can't detect him and all gang up on your Lord.
That is in fact what happened! I wondered about that already. I did "Shield training" (for Lord) and "Stealth training" (for Rogue) in the cellar of the temple in Arnika, where I let ghosts attack my party. They mostly attacked the Lord! Only 1 out of 10 attacks was for the Rogue. And when I put the Rogue in the front line, they stopped attacking after a while and retreated... that was annoying. But it confirms what you said. They all ganged up on the Lord.
So:
Casting school mostly focused on support + Hybrid caster + Dumping spellcasting stats = Poor offensive spellcaster
Who would've thought?
(And even then, offensive magic in Wizardry 8 isn't as powerful as in most other RPGs)
I'd probably focus on healing and buffs such as Superman for the Lord.
I don't think you've picked a very powerful pair. Why didn't you go with two hybrids? This party seems needlessly gimped. Did you pick classes at random?
I kinda agree. It survives for a while but something feels off.
No, I didn't pick them at random. Actually I put a lot of thought in them. Initially I wanted to do a Solo-Run. But then I recalled all the tedious "powertrainings" required, like spamming cast charm, spamming heal, spamming rest all, hours of inspecting traps, multiclassing etc. This honestly turned me off. Then I thought why not make a second character who complements the lacking skills of the Solo-Character? Then I could skip all these annoying powertrainings and multiclassing and just "play naturally". So I looked for a suitable combination.
There are at least 2 requirements to successfully beat the game, which are:
a) Locks&Traps skill to open doors with tumblers
b) Sufficient protection against magic
Lord:
+ can cast the most required protective spells against magic attacks (Magic Screen, Sould Shield, Purify Air)
- lacks Locks&Traps skill (which are essential to complete the game) and cannot learn Knock-Knock
Rogue:
+ has the Locks&Traps skills
- lacks any magic protection
So in essence they would complement each other. Additionally I thought they could master any possible situation standing side by side in combat:
* Lord is decent ranged attacker with spells (plus a really good mass effect spell later) <-> Rogue is decent ranged attacker with bow
* Lord is decent melee attacker <-> Rogue is decent melee attacker
* Lord is difficult to hit with high shield skill <-> Rogue is diffcult to hit with high stealth skill
* Lord has decent healthpoints (plus the bonus of health regeneration) <-> Rogue has decent healthpoints
None of them would ever get bored in combat. Each one could do something in any situation. None of them could be killed easily (unlike the usual setup with Tank + GlassCanon). Both them could probably use some of the best melee weapons in the game (which give an instakill percentage) so even melee combat with lots of enemies should be painless. And the very few spells of the Lord would be an advantage because he could just use the same ones in combat and therefore "naturally" train his magical abiltities without "powertraining". That were my thoughts. But yeah... eventually I'm not so convinced anymore.
The only thing where the Lord really profited from was his "Health Regeneration" and only in the beginnings of the game. When I did his shield powertraining (the only powertraining I did), he absolutely didn't require any potions at all. Just stood there in defending position, got attacked and right afterwards healed himself. Probably one of the fastest powertrainings ever. That now being said... I think this could be done by Rogues or other Classes as well, if they got an Amulet of Healing. But that Health Regeneration was also one of the reasons I chose the Lord. As an additional safety measure in combat, so he should survive the longest (but as it turned out he was often killed before the Rogue). Later in the game the Health Regeneration also did not seem to be sufficient anymore, because the attacks from others were just too strong. So I imagined his innate regeneration ability to be greater than it actually was.
