Items - Comparing Efficiencies

Looking forward to the Damage Reduction section. Great guide!

i think the correct calculation for critical items is: Total_Effective_DMG_with_item - Base_DMG which means ex.Crystalis (TotalDMG*0.2*1.75+TotalDMG*0.8)-BaseDMG

TotalDMG= CrystalisDMG + BaseDMG with base i mean rest of dmg without the crit item.

I think the stats for the daidalus are outdated. Now crit. chance is 25% and critical DMG is 240% at the cost of 2550 gold making it less gold efficient than 1 crystallys and even 2.

Absolutly brilliant. This helps sifting thru items and making unconscious decisions about the effectiveness of an item based on its name or picture (stats are confusing). I would recommend this guide for any player out there. Very gg, nice job.

Ah, thanks for pointing that out. I guess I must have used the previous value (1.89) for Iron Branch on accident.

Helpful +1, you must really love math. xD

This is a great idea. +1.

As a new DOTA player, understanding the items was/is for me the next big learning curve from understanding the core mechanics / flow of the game (yes even before Heros themselves), so a guide like this is really great when pulled together with the general understanding of builds and building up your items through out a game from early / mid / late.

Nice job - keep it up !

Thanks. Looking at the numbers I'm beginning to see why Iron Branch is such a popular starting item among better players.

This is an excellent idea. I'm by no means a 'good' DotA player, but even I understand the benefits of knowing which items are more cost efficient. Sending a + 1, and I'll be checking in on this every once in a while. Keep up the good work!

Thanks =P
I've pretty much finished up the damage section, though I'm sure people will ask about items I omitted.

The damage part took so long because there is A LOT of manual calculations due to the fact that many of the items offer damage modifying effects. Most of the rest of the guide should take much less time because I can basically just build an excel spreadsheet with the formulas built in, then past it into here ;)
