A Tribute to Dedicated Insanity

From Daelo, Lead Designer Encounter (Source)

You can use:
• Any item below item level 245.
• The item level 245 set pieces that drop from 25-player Trial of the Crusader but also appear in the 10-player Tribute Chest.
• Any gear that drops in 10-player Trial of the Crusader or Trial of the Grand Crusader, including item level 245 Trial of the Grand Crusader drops and item level 258 cloaks from the 10-player Tribute Chest
• Any item level 245 items purchased with Badges of Triumph.

You cannot use:

• Any item over item level 245 except for the 10-player Tribute cloak.
• Any higher item level loot introduced in future patches (25 player Onyxia 245s, Icecrown loot in the future, etc.)

You CAN NOT use Relentless PvP gear, our resto druid slapped a few pieces on to replace some of his ToC25 gear and we did not get this achievement. Next week, he corrected this, and we got it.

Reading + Following the post made by Daelo (Lead Design Encounter) is the best way to go when planning for this achievement

I'll provide my own little advice for this it:

Unless you are a strict 10m guild, this achievement will require some planning. Give your group a full week or so notice to plan on what pieces to replace. Between the 10 of us, we usually had an average of 2-4 pieces or so that we had to replace. Some people kept their old gear, others vendored or DEd it, sadly.

Here are some great places to replace pieces of gear if you're in a hurry:

- Badge gear, from ALL four sources (Triumph, Conquest, Valor, Heroism)
- Craftable gear of any kind, most preferably the ToC patterns.
- PvP Gear Furious and lower
- Any semi-decent BoE epic from the AH
- If all else fails, grab a crappy BoE blue from the AH. Assuming it's just one piece, it won't drastically effect your performance.

Now, with your downranked gear you'll have to finish ToC10 with no wipes. Overall the DPS will be a bit lower, the healing a bit more stressful, but just keep your cool, use your flasks + food buffs for every attempt, bring plenty of haste/wild magic/indestructible potions to compensate for the lack of gear, and do the same strategies you did for Insanity, and you'll get this achievement.

Since patch 4.0.3a, this achievement has become Feat of Strength and is no longer obtainable by players because the tribute system is no longer in place.
Enjoy your unique, pretty rare title :)
