I was converting an old adventure, UK7 Dark Clouds Gather, for use in my 4E game. It is based on characters of roughly 7th level. I noticed that towards the end, giants began to feature prominently in the encounters.

Now, giants are normally paragon-level standard monsters. However, a party of 7th level characters would get decimated by a paragon-level monster. So I looked at the encounter again, which only called for one giant. This seems to work well. Then I remembered this quote from the DM tips:

I'm starting this thread a place for 4E dms to post tips for other 4E dms based on their experience running 4E. ... Monster Stat Blocks Monster stat blocks should be considered as being relative to the party... Example 1: In heroic tier gaming you might have the stat the local militia of a town as level 3 skirmishers or soldiers. This is a good reflection of their capabilities relative to a heroic tier party. However, as the heroes advance this stat block becomes obsolete, so when they are at paragon tier if you had need of the town militia again, you might consider restating them as higher level minions...

So I figured I could convert the giants into heroic-tier solo monsters. This is an example of the above in reverse: paragon-tier standard monsters could be converted into heroic-tier elite or solo monsters.

I wish to post my work to both show examples of what I am talking about as well as to get feedback on my work. Let me know what you think.

Example One called for a frost giant and a winter wolf. I designed this encounter as a young adult frost giant hunting with his winter wolf pup.

Thoughts?

Just use the monster builder application from WotC, it will level any monster published in the game up or down any number of levels.

It can do elites, minions, and solos as well, although I found that it will not modify defenses for elites or solos as you have to choose which ones to add +2 to.

And you can edit the stat block anytime you want.

When I convert adventures from previous editions I don't hold to the same level band that the original adventure did. 4th Edition is based on a 1-30 range rather than a 1-20 range, but those 30 levels are designed to cover more or less the same scope of adventuring that the old 1-20 range did. As such, I usually multiply the original adventure's level band by 1.5 when converting. An adventure designed from 7th level characters in previous editions would thus see a conversion designed for 11th level characters in 4th Edition.

I haven't had a chance to look over your stat blocks, but in case you decide to bump your PCs' starting level to paragon tier, this encounter is basically done for you. The frost titan avalanche is a level 14 solo brute that appears in Dragon #377, and winter wolves are level 14 skirmishers from the Monster Manual 2. A party of 11th or 12th level will be challenged strongly by an encounter featuring these two, but can still probably pull through.

When I convert adventures from previous editions I don't hold to the same level band that the original adventure did...

Two comments:

1. The current party will be 7th level when I am ready to run this, so I decided to stick with that level.

2. With first and second edition modules, they often mix monsters in the adventure that wouldn't necessarily work in 3E or 4E. For example, earlier in this adventure they fight small warbands of orcs and such, which is typical of middle heroic tier. However, later on there are giants and other creatures that are middle paragon tier. Thus I rarely convert modules straight across.

Instead I use the overall plot and adventure summary to drive the adventure, but I adjust the encounters towards the party level. Thankfully this adventure is much easier to convert than most I have in the past.

I did the same recently with a hill giant that I wanted a 2nd-level party to encounter. I basically wanted an uncoordinated sack of hit points so I went with a 4th-level solo brute. It was just right.

The other option is to use a higher level minion version of the same creature. Defences and hit points, IMO, are simply two sides of the same coin (which I why I never agreed with solos getting defence bumps when their hit points are a multiple of standard or elite creatures). So if you have a high level minion with high defences, chances are it can take quite a few attacks by a lower level party before that single hit point is removed.

The other advantage of the high level minion is that even if it hangs around for a few rounds longer than expected, it won't be dishing out too much damage. That said, it could be a bit boring but may be worth a try in certain circumstances.

It can do elites, minions, and solos as well, although I found that it will not modify defenses for elites or solos as you have to choose which ones to add +2 to.

I believe the new monster design philosophy has moved away from that bonus, which was always a bad idea IMO. MM2 elites and solos don't seem to have that extra boost, because anti-flank powers are more useful and fun.
