Formation fighting may be awesome historically, but when overused in D&D it feels uninspired and static. Encourage movement, either with the carrot or stick approach. This is an entire topic unto itself. But for starters, include multiple routes to a destination, branching pathways, and circular paths. Also, think vertically and in 3D.

A chimera guarding a door in a tomb is good for a smaller group but not for such a large party. Instead, you want to change that to: There's a tomb complex (the encounter zone) with several areas like a spell-warded noble's vault, a hall of funerary totems and riddling broken statues, an ossuary where the blessed progenitor of the family supposedly is interred along with his 40 priest-spouses, a trapped entry foyer, a hidden treasure vault for a bountiful afterlife, a false gate (maybe a mimic), and the gate room with its stone surface polished to an eerily reflective degree. These areas interconnect. </p><p></p><p>Channels of oil flow through special alcoves at human waist height, with an occasional lump of wax in the channel. A breeze blows through the complex from east to west, thanks to the design of tiny air passages on the easternmost wall.

Each chimera has a different colored dragon head: The red-headed one can light the oil channel, creating bright light (yah!) and also some minor walls of fire as an obstacle for the PCs (not so yah). The green-headed one breathes its cloud of poison gas, letting that drift across the tomb complex carried by the breeze. And the blue-headed includes the door in its breath attacks, causing a ricocheting bolt of lightning to to circumnavigate the entire tomb complex thanks to the orientation of the reflective stones.</p><p></p><p>Now you have multiple ways for a large party to interact with the situation. Do we plug the airways or try to use them to clear the gas? Do we want the bright light or do we look for a way to drain oil reservoir to end fire hazards...or even try to use it to our advantage? Do we try to break the reflective stones or try to discern a way to rotate them to our advantage? Do we try to figure out which gate is the right one and devise a means to open it, hoping to avoid the chimera altogether? </p><p></p><p><strong>6. Dilemmas</strong></p><p>Finding a good dilemma for your group of players (and their characters) is an art. But once you find one, you can step out of the way and let your large party debate among themselves.

[QUOTE="Quickleaf, post: 7024790, member: 20323"] Hey, I've been in your shoes, just with a party of 7, so not quite so big. A couple "thoughts from the DM road..." [b]1. Change travel[/b] Simple change: long resting requires comfort/security that is rarely present when journeying in the wilderness. Basically, you need some kind of sanctuary where you don't have to worry about keeping watching and whether owlbears are gonna getcha. So the "journey" becomes the "adventuring day." Useful if you have usually have 1-2 encounters between rests, like you said. [B]2.

Don't send them into kobold warrens, unless they're really into that sort of thing. Think the Mines of Moria as Peter Jackson imagined it on film, with huge chambers and pillars supporting a roof so high you can scarcely see it in torch light. [B]4.
