I am trying to get to this place called Cove in UItima 4 to get the candle of love.

But there is no way to get there on foot, the only way it seems is to get a ship in the lake, but there is no ships, is there anyother way to get to Cove?

You can use the Blink spell directly from west of it. Use magic gems or the View spell to help line you up. If you are having trouble, try getting a bit further away, as the Blink spell might be overshooting.

Did it, thanks for the help :)

You can either wait for a ship to spawn in the lake, take it over and sait to Cove, or you take over a ship in the sea (more likely to spawn there) an then sail into a whilpool which will take you to the lake.

Now I have 2 questions:

1. I already know the Mystic Armor and Sword are needed to even defend yourself in the Stygian Abyss, but are they also the Strongest Weapons in the entire Game?

2.Do I really need all 8 party members, my current party is 6, only the Tinker and the Sheperd remains, but do I really need them?

1) The Mystic Sword has an attack rating of 255, making it the strongest weapon in the game, but it only works at close range. The magic bow has an attack rating of 80, the magix axe has 96 and the magic wand has an attack rating of 160. While they are weaker than the Mysic Sword, they can attack across the screen, allowing you to potentially take out enemies before they even come in range, or if it's a ranged enemy you won't have to eat damage while trying to get close

2) You must have a full party when entering the last shirine in the abyss, but you can just let the part members you don't like get killed and resurrect them before entering the last room. That way they won't slow you down during combat. Just make sure you have enough resurrection spells and someone who can cast it should still be alive.

Also how do I get Mandrake Root?

Its says there are in the Bloody Plains but how do I get them?

Samething goes for Nightshade?

The Bloody Plains are west of Vesper, just over the mountains. There is a single square of swamp there. Search it when both the moons are dark. I don't remember which reagent you get there.

The other spot is in the forest southeast of Skara Brae. Again, you can only find it when the moons are dark. The spot is marked on the map you linked in your first post, about halfway between Skara Brae and Destard.

Another one;

Why can't Katrina join me?

She says I am not experianced enough for her to join me, so whats the requirment, I assume you have to have the main character and max level?

Your level determines the maximum number of followers: just you on first level, you and one companion on second level, you and two companions for the third level... You also have to be level 8 when entering the abyss or you will get thrown out in the last room. In addition you must master all 8 virtues, learn the word of passing (or look it up on the internet), learn the one Axiom (it's infinity, due to an overseight no one in the game actually tells you) and you must posess all eight coloursed stones and you must be in possession of the book, bell and candle. It's not needed technically, but you should also find the wheel of the HMS Cape so your ship has a better chance against the pirate ships near the Isle of the Avatar.

Everyone has to be level 8 or just MY character when it comes to the Stygian Abyss?

Just your main character.

OK I am stuck in the Hythloth dungeon on the sixth floor.

Map:

In the first room (the pink squeres in the map) on the sixth floor there is no exit on the west, I tried exploring the whole room and no secret button to open the door.

Forgive me if you are confused, I just need help.

It's a well-documented bug. The reason you can't find one is because there isn't one, though there's a patch out there to fix it, included with Pix's Ultima Patcher (check the resource collection sticky thread).

Or rather install a patch I cast the up spell which makes me go on floor above a dungeon......yeah.
