Very good sir (or madam). Are you new to the game?
These are good tips. Where are you finding stone bricks to pick up, though?
A big tip I always dispense for any dungeon-diving is
WALK don't run. Running blindly (like the way my 16 y.o. nephew does it) can trigger traps. Next thing you know, you're in a spike pit (or being tossed up to the ceiling in a giant masher device!
Also, many traps are
centered--they have been placed in the
center of the room (or hallway, or causeway, etc.). And if the trap has some sort of trigger, often this will be centered too. Sometimes it makes sense, therefore, to explore from the
sides of the area the PC is in.
One main exception to this are those awful firing stones. I'm forgetting the official name for them...they often shoot
red magic at our characters, and are usually placed in areas which we haven't got much space to move around (a narrow causeway, for instance). And the thing that svcks about them is sometimes they can do some hefty damage, especially to low-level characters. They make me mad sometimes.
On the topic of Welkynd stones: I've had a lot of different characters over the years. some of them use Welkynd stones for their actual purpose: recharging magicka. Others will leave them where they are, for a variety of reasons.
