Forgotten Tales

If a monster's movement image files were blanked except for resting position, they would either be invisible while moving, or only blink in and out as the frames passed the resting position. This would be awesome visually, and challenging to target if totally invisible while moving. Haven't tested with editor yet, as altering the movement files isn't so easy for me, but would definitely be interesting.

Another idea is reducing the size modifier on dragons back to 1.0, resulting in dragonets/ dragonlings/ etc. These could be weaker than the originals, yet spawn more at a time and move faster.

Any thoughts?

Hmmm interesting, and I think, actually "new" ideas in boss monsters...

The invisible moving monster, that you can only see when stationary.. cool... I'd like to note though, the attack anims would need to be visible; as likely, when stationary, it would be attacking, not sitting idle.

The dragonling thing would be neat as well. A boss that spawns enemies to harass you as you're fighting.... yes it could work... also, would encourage players to not solo this kind of boss as well.

I really like this line of thinking. Would force players to team up with others. Could make for some interesting alliances.

yeah, neat ideas that hard part is this - if 2 or 4 level 500s can work together to kill it, and it's worth killing (meaning good xp + drops) then a 2000 (or 10000 for that matter) will come farm it, and the 500s won't have a chance anyway... you can make the dungeon level restricted of course, but then it's much harder to find people to team up with, because they need to be close to your own level

not impossible to get it right, just difficult

As blitzcraig said, limiting dungeons by level could work.
We already have this mechanic in fact; the event portal is rigged this way.
So, perhaps, a dungeon that is level related, that spawns a boss and mobs that are level related....
Yes, perhaps it could be done....

Invisible monsters should not be immune to area effect spells though. And should briefly become visible when burning (whether from green flow or fire arrows).

Slow spell should still work, but not make monsters visible.

I like the idea, however I'd just like to add that if there are drops involved that it'd be given to a player randomly, based on the amount of damage they did in total. Like if you did 10% damage, you'd have a 10% chance of getting the item if it dropped. Something to that effect anyway, just not always given to the person that did the most damage.

Or perhaps some way to make a "group" that if you're in the group fighting the boss, all damage in that group is added up against another group, the group that did the most damage would win, and then an even split chance of getting the drop within the winning group. If it's just 1 group, then the drop would just be randomly given out to any player in the group. This would encourage people to play more supporting roles for the group rather than just trying to deal the most damage and get the drop.

I love the idea of co-op playing in general, I'd rather play with people than against them

I certainly enjoy entertaining the idea of a boss monster that would require players to team up in a group to be able to defeat said boss.
