That's an odd situation. Off the top of my head, I can't think of anything that would cause it.
Can you post a screenie or a copy of the combat log, so that we can take a look?
No need to apologise for bad English - yours is better than that of some native English speakers on these boards. 
Oh, and welcome to the forum! (I'd normally say welcome to the game, but have no idea how long you've been playing.)
The wisdom of Shadowe: Ghostraptor: The Shadowe is wise ...; FFM: Shadowe is no longer wise.
; Techbot_Alpha: Also, what Shadowe said. It seems he is still somewhat wise 
; Bull Throttle: Shadowe was unwise in this instance...; Rock_Powerfist: in this instance Shadowe is wise.; Techbot_Alpha: Shadowe is very wise *nods*; Zortel: *Quotable line about Shadowe being wise goes here.* Would be interesting to see that screenshot. A spawned rubble should do hardly any damage in comparison to its 'parent'. I've certainly never seen it happen.
A couple of possibilities come to mind:
1) Rubble spawned as wrong level, and was +lots to you
2) Rubble was affected by a damage buff (unlikely)
3) You where affected by a resistance debuff.
4) You accidently turned off a shield, or it went down without you noticing.
I really should do something about this signature.
5) Rubble have +200% Scourge but no one told us.
6) Bug!

>< i was going to post it ..then i see the windows are not visible...in the screenshot there are only me and some stone on the floor ç_ç
im sorry ç_ç
hehe the default is for a screenshot to hide the user interface components. You can override that in the options. Oh well, we'll just have to assume it was a debuff or a lost shield or something unless it happens again 
PsyWitch, do you have chat logging turned on?
If you do, then your chat log for the day will have the detail in it. (And if you don't, I recommend switching it on.) I'm sure someone will be able to recommend a good chat-parser (I seem to remember one called Spad's, but that might just be my pathetic memory) so that you can get rid of all the extraneous stuff.

Shadowe's pathetic memory is correct. 
Though Spad's is a bit out dated and probably not equiped to filter out combat and power related loggings.

If you have nothing useful to say, you have two choices: Say something useless or stay quiet.
I dont know if its a bug, but i have to ask you this episode because i really cant understand it.
I was in a mission alone, and i killed a Bedrock (golem of stone by Devouring Earth) when he explode he spawn a minor mob "Rubble".
This one should do lesser damage than Bedrock... isnt it?
He dealt lesser damages usually, but one moment ago he killed me dealing 264 damages!(from a standard damage of 60-90 o.o) i screened the text message that writed the damage but i didnt post it because i dont know if it can be useful or not.
The two questions are:
Can mobs deals massive damages sometimes and in which situations?
(P.S. im blaster lvl 30 and the mob was 30 too)
thank you for the consideration (sorry for my bad english^^")
